    Abstract:Silicon microring modulators have huge potential for applications in co-packaged optics (CPO) and optical I/O (OIO) owing to the superior bandwidth, small footprint, and inherent wavelength multiplexing characteristics. To enable efficient and robust optical transceiver systems, codesign and cosimulation environments are essential for optimization of photonic devices, transceiver circuitry and electronic-photonic integrated circuits (EPIC). We introduce a comprehensive equivalent circuit model for single- and dual-segment silicon microring modulators (MRMs), which accurately capture the device behavior during high-speed modulation. This model includes electrical parasitics, nonlinear optical steady state and dynamics, and thermo-optic effects. Model parameters are extracted by curve fitting MRM optical transmission spectrum and small signal characteristics. The simulated eye diagrams exhibit excellent alignment with the measured eye diagrams at data rates of 80 Gb/s and 106 Gb/s. A cosimulation environment with a MRM driver in 28 nm CMOS and a MRM in 130 nm silicon photonics is demonstrated on an electronics design automation (EDA) platform. An optical eye diagram at a data rate of 212 Gb/s PAM8 is successfully achieved by optimizing the driver equalizer and the MRM two segment ratio. Then an EPIC with photonics-electronics closed-loop feedback control algorithm is demonstrated, achieving a significantly larger eye opening after thermal tuning, thanks to the accurate equivalent circuit model of the MRM. ? 1983-2012 IEEE.

    Abstract:Fluorophosphate glass has excellent characteristics such as low nonlinear refractive index, anomalous partial dispersion, low phonon energy, high UV transparency and high rare earth doping concentration, etc. The two anion ions of fluorine (F) and oxygen (O) and their F/O ratio in fluorophosphate glasses provide important structural characteristics of the specific glass. To explore this, a series of fluorophosphate glass samples with theoretical F/O ratios ranging from 1 to 7 were prepared, Raman spectroscopy and 31P nuclear magnetic resonance (NMR) spectroscopy were mainly employed to elucidate the structural polyhedrons made of the network chain. The underlying correlation between the Qn units and F/O ratio was explored, i.e., the Q2 unit dominate when the F/O ratio is less than 0.3, and predominantly Q2 or Q1 unit is predominant as F/O ratio ranges from 0.3 to 1, it comes to be Q1 or Q0 unit as F/O ratio further increase to 4, while it becomes Q0 when the F/O ratio is greater than 4. The applicability of this interval estimation was verified by comprehensive analyzing a variety of structural results of fluorophosphate glasses with various glass compositions. The explored interrelation between the F/O ratio and structural property is of great significance for developing low nonlinear and UV transparent fluorophosphate glasses. ? 2024 Elsevier B.V.

    Abstract:We present a four-channel polarization-insensitive silicon photonic (SiPh) wavelength division multiplexing (WDM) receiver, incorporating a polarization splitting grating coupler, dual-ring filters and bidirectional photodiodes. This design achieves an ultra-compact footprint of 1 mm × 0.2 mm with a polarization dependent loss (PDL) of 0.58 dB or less. Four clearly open eye diagrams at a data rate of 112 Gb/s PAM4 are obtained. Furthermore, we demonstrate the hybrid integration of the SiPh chip with a 28 nm CMOS transimpedence amplifier (TIA), resulting in an impressive energy efficiency of 1.34 pJ/bit at a data rate of 100 Gb/s PAM4. Sensitivities of -13.4 dBm and -5.6 dBm are achieved at data rates of 50 Gb/s NRZ and 100 Gb/s PAM4, respectively, under KP4 forward error correction (FEC) threshold. ? 1983-2012 IEEE.

    Abstract:We describe the experimental finding of three kinds of bound solitons in the Erbium-doped fiber lasers based on saturable absorber of black phosphorus. The passively mode-locked laser can obtain stretched-pulse state, double-pulse and four-pulse bound state with the sech2-shaped pulse profile. The laser can also realize Lorentzian autocorrelation trace with the duration of approximately 562 fs and deliver Lorentzian double-pulse bound state with pulse separations of approximately 5.04 ps by properly adjusting the polarization state. This project demonstrates that the same fiber laser can obtain different types of bound state pulses, which lays a foundation for further research into bound state pulses. ? 2023 Elsevier Inc.

    Abstract:Planar microlens components are highly desired in micro-systems for their compactness and ability to integrate with other planar elements. In this paper, we propose an alternative facile approach to producing positive planar microlens components by infilling concave microlens featured glass encapsulation with high refractive index chalcogenide polymer. The presented refractive microlens components have several advantages: cost-efficient to process, high transmission in broadband spectrum, the ability to generate real focus and real image, and being well-protected by its planar glass encapsulation. Both single and arrayed samples were fabricated to demonstrate the effectiveness of the manufacturing process. The optical properties of the fabricated samples, including phase modulation, imaging performance, and spectrally operational region, were thoroughly characterized. Wavefront calibration with the prepared sample revealed its potential application in practical engineering fields. ? 2024 Elsevier Ltd

    Abstract:We report the development of an all-fiber polarization maintaining (PM) optical frequency comb using a mode-locked figure-9 laser with a low self-starting pump threshold. We have achieved self-starting mode-lock for repetition rates (fr) from 70 MHz to 109 MHz. At a repetition rate of 109 MHz, mode-locking can be achieved for a pump power ranging from 187 mW to 880 mW. To the best of our knowledge, this is the lowest pump power reported for PM figure-9 erbium fiber lasers with repetition rate over 100 MHz. By optimizing the pump power to 238 mW, we have achieved an output power of 5 mW, center wavelength of 1566.2 nm, and 3-dB spectral bandwidth of 20.5 nm. The repetition rate has a high signal-to-noise ratio of 95 dB at a resolution bandwidth of 300 Hz. We have studied the spectral characteristics of the laser under different cavity lengths and pump powers. Additionally, we have stabilized the repetition rate using a GPS-Rb disciplined RF reference. The fractional instability of the repetition rate is measured to be 4.67×10-12 at 1 s and 9.22×10-13 at 10 s over a measurement of 11 h. Our findings demonstrate that the developed figure-9 comb is robust, compact and has the advantage of high stability and low power consumption. It offers a cost effective solution for future outdoor comb applications. ? 2024

    Title:Numerical simulation of dynamics behavior of pulsed-DC helium plasma jet confined by parallel magnetic field at atmospheric pressure

    Abstract:A two-dimensional axisymmetric fluid model is used to simulate the dynamics behavior of an atmospheric-pressure helium plasma jet in the presence of a parallel magnetic field. The plasma jet is generated in a coaxial dielectric barrier discharge (DBD) driven by pulsed direct-current voltage. Comparative analysis of the plasma jet with and without the parallel magnetic field indicates that a slightly thinner plasma sheath inside the tube is present with the parallel magnetic field as a result of the decreased accumulated electrons on the inner surface of dielectric tube. After the streamer propagates outside the tube, a little more concentrated electron distribution in the annular wall is observed by applying the magnetic field because of the reduced electron diffusion in the radial direction and the confinement effect of the magnetic field on the electrons in the avalanche heads. The tiny reduction in the length of plasma jet is attributed to the E × B drift of charged particles. These results demonstrate that the parallel magnetic field has no apparent effect on the propagation of the plasma jet, and it contributes little to the performance improvement of the coaxial DBD, which agrees well with the previous experimental observations. This little impact of the parallel magnetic field on the coaxial DBD plasma jet may result from negligible contribution of the memory effect to the sole discharge pulse as well as the weak confinement effect of the applied magnetic field on the surface electrons that moves along the magnetic field lines under electrostatic repulsion. ? 2024 authors.

    Abstract:Based on surface plasmon resonance (SPR), we proposed a tunable chalcogenide solid-core anti-resonant fiber (SC-ARF) polarization filter. The purpose of introducing the SPR, which is excited by coating the inner wall of the cladding tubes with a gold film, is to achieve a discrepancy between the confinement loss of two polarized fundamental modes (FMs). The full-vector finite element method (FV-FEM) evaluates the impact of fiber core radius, cladding tube radius, cladding tube wall thickness, and gold film thickness on the polarization filter characteristics. The results show that when the thickness of the gold film is 30 nm and the fiber length is 4 mm, the filter bandwidth can simultaneously cover the S + C + L optical communication band and reach 248 nm, and the extinction ratio (ER) value reaches -377.46 dB. Moreover, we also confirmed the tuning effect of the gold-coated cladding tube wall thickness on the resonance wavelength. The proposed fiber polarization filter has potential application value in optical fiber communication and transmission. ? 2024 Elsevier Ltd

    Abstract:Laser based range measurement system plays an important role in both scientific and industrial areas. Soliton microcomb (SMC) based dispersive interferometry (DPI) method has shown the advantages of high speed, high precision, and compact size in ranging systems. However, due to the high repetition rate of SMCs, it results in a small non-ambiguous range (NAR), which impacts the practical application of SMC based ranging systems. Furthermore, when the measured distance is close to N times NAR, it is difficult to extract the distance information including the delay time and direction. Here, we introduce frequency scanning and prime number algorithm to an SMC based DPI ranging system. The frequency of SMC can be scanned over one free spectral range (FSR) by sweeping the pump frequency and the resonance of the microresonator synchronously. The interference spectra are recorded when the frequency is scanned every 1/im(im = 2, 3, 5, 7..., a list of primes) FSR, and the NAR can be extended by ~ √ 2∏im times through interpolating the recorded interference spectra. We experimentally verify the feasibility of the proposed ranging system, and the NAR is extended by 3 times. Furthermore, we extract a small delay time of 6.859 fs with a standard deviation of 1.128 μm, which cannot be determined by the SMC with original repetition rate. The proposed ranging system can extend the NAR without any auxiliary rough measurement systems, and the detectable distance over the full range can be achieved. ? 1983-2012 IEEE.

    Abstract:Chalcogenide glasses with less optical losses are highly demanded as optical materials for micro lense, waveguide and fiber devices. However, it is still challengeable to reduce the optical losses in infrared chalcogenide glasses with opaque visible light. Herein, an improved 3D distribution of scattering sources is established in this study to test and compare the concentration and distribution of defects in As38S62, Ge28Sb12Se60 and As40Se60 chalcogenide glasses. Furthermore, by comparing the scattering images of serial As40Se60 glass prepared under various melting, quenching and annealing temperatures, the preparation process was optimized to reduce its scattering loss. In addition, this study introduced a scheme that could be widely applied to optimize processing of other infrared glasses and devices glass to reduce their scattering losses. ? 2023 Elsevier Ltd and Techna Group S.r.l.

    Abstract:We demonstrate the low noise operation of a figure-9 1.5-μm Er:fiber laser constructed by all polarization-maintaining (PM) fiber and fiber components. Starting from the original rate equations and nonlinear Schr?dinger equation, the cavity roundtrip evolution toward stable mode locking state is present. The radio frequency spectrum shows a 94.6-MHz fundamental repetition rate with up to 100 dB high signal-to-noise ratio. The net dispersion is tailored to near zero by incorporating and optimizing the length of PM dispersion-compensating fiber in the cavity. As a result, an integrated root-mean-square relative intensity noise of 0.0026 % [1 Hz, 1 MHz] and 10.8-fs timing jitter [100 Hz, 1 MHz] at the fundamental repetition rate are measured. We also lock the fundamental repetition frequency to a stable radio frequency reference and an in-loop relative stability of 2.1 × 10?12 at 1-s gate time is obtained. ? 2024 Elsevier Inc.
