We propose and demonstrate compact optical mode and polarization filtering devices on a lithium niobate on insulator (LNOI) platform. The subwavelength grating-based high-order mode pass filter and TM-pass polarizer are designed and experimentally demonstrated successfully. The measured insertion losses and extinction ratio at 1550 nm are lower than 1.9 dB and larger than 30 dB, respectively, while the device lengths are only about 50 μm. © 2022 SPIE.

We investigate the integration of quantum key distribution (QKD) into classical optical communication links based on a field-deployed uncoupled-core four-core fiber. We experimentally characterize inter-core spontaneous Raman scattering (IC-SpRS) and evaluate the impact of IC-SpRS and dark counts on QKD performance as the classical traffic load is varied when three cores are used for classical WDM transmission and one for QKD.

Doubly resonant photonic crystal cavity using merged bound states in the continuum

引用

Physical Review B 2023年第16期107卷 165406-165406页

作者： Rui Ge Xiangmin Liu Xiongshuo Yan Xianfeng Chen Yuping Chen State Key Laboratory of Advanced Optical Communication Systems and Networks School of Physics and Astronomy Shanghai Jiao Tong University Shanghai 200240 China Shanghai Research Center for Quantum Sciences Shanghai 201315 China Collaborative Innovation Center of Light Manipulations and Applications Shandong Normal University Jinan 250358 China

In this work, a doubly resonant photonic crystal (PhC) cavity using the merged bound state in the continuum (BIC) is proposed to obtain a higher second harmonic generation (SHG) efficiency. First, by scanning geometry parameters, the accidental BICs and a band-edge mode outside the light cone can be obtained. Then, as the lattice constant or the thickness of the slab is adjusted, the accidental BICs will merge. A supercell with large and small holes is constructed and the band-edge mode outside the light cone can be matched with the merged BIC mode. Finally, the heterostructure PhC cavity is designed. The merged BIC show a high quality factor of about 2000 for the PhC with finite size. The value is four times larger than the one in isolated BIC (about 500). Consequently, the SHG efficiency of the lattice constant near merged BIC of about 4800% W−1 is higher than the one of the isolated BIC (about 1000% W−1). This work is expected to provide guidance to the efficient nonlinear conversion in a small volume.

optical ranging is a key technology in metrology. optical frequency combs are shown to provide several advantages in light ranging, offering high precision with high acquisition rate. However, performance of traditional ranging systems based on microcombs is limited by the short ambiguity distance and non-real-time processing. Here, we show that dual-comb ranging system using coherent Kerr soliton microcombs and optical switch realizes extended ambiguity distance and provides a route to real-time processing. The ambguity distance is extended to 3.28 m from about 1.5 mm and the uncertainty reaches about 1.05 × 10−7, while the system is compatible with low-bandwidth detectors. Combining coherent microcomb ranging systems with special FPGA could enable comb-based real-time ranging systems for several applications such as industrial process monitoring. © 2023, CC BY.

Optimization of optical signal-to-distortion ratio in a channel-interleaved photonic ADC via a coherent multi-frequency RF driver

引用

Chinese Optics Letters 2021年第8期19卷 138-143页

作者： Junyan Li Na Qian Shiyu Hua Weiwen Zou State Key Laboratory of Advanced Optical Communication Systems and Networks Intelligent Microwave Lightwave Integration Innovation Center(iMLic)Department of Electronic EngineeringShanghai Jiao Tong UniversityShanghai 200240China

A microwave-chip-based coherent multi-frequency RF driver is developed for a channel-interleaved photonic analog-todigital converter(PADC) system, which comprises a multi-class optical demultiplexer and supports a sampling speed of 40 GSa/s. The generated signals from the RF driver are adjustable in both amplitude and phase. We analyze the relationship between the characteristics of the generated RF driver signals and the demultiplexing performance in theory based on the optical signal-to-distortion ratio(OSDR). It is the most effective parameter to evaluate the performance of the demultiplexer in a PADC system without an electronic analog-to-digital converter. By precisely adjusting the amplitude and phase of signals, the OSDR is optimized. The results verify the compatibility between the RF driver and the PADC system.
