Jianyu Zheng,Mu Xu,Lixian Wang,Zhongle Wu,Lin Cheng,Ibrahim Khalil,Jianguo Liu,Ninghua Zhu,Sophie LaRochelle,Gee-Kung Chang +9 more
TL;DR: This work proposes and demonstrates a bandwidth-efficient full-duplex millimeter-wave radio-over-fiber access link based on orthogonal phase-correlated modulation enabled by polarization maintaining fiber Bragg gating and eliminates backscattering noise in the upstream link.
Journal ArticleDOI
Switchable microwave photonic filter based on a dual-parallel Mach-Zehnder modulator.
TL;DR: A switchable and tunable microwave photonic filter based on a dual-parallel Mach-Zehnder modulator (DPMZM) and a tunable optical bandpass filter (TOBPF) and widely tunable in terms of bandwidth and center frequency.
Journal ArticleDOI
A Novel Grating Coupling Coefficient Extraction Method for DFB Laser Diodes Based on Side Mode Spacing
TL;DR: In this article , a method to extract the grating coupling coefficient of distributed feedback (DFB) lasers by comparing the theoretical and experimental values of the side mode spacing is demonstrated.
Proceedings ArticleDOI
Small-signal and large-signal performance test of high-speed optoelectronics devices
TL;DR: In this paper, a measurement method for determining the reflection coefficients and frequency responses of semiconductor laser diodes, photodiodes and EA modulator chips is presented, and applications of the developed measurement methods are discussed.
Proceedings ArticleDOI
Multi-microwave sources generation based on dual optical frequency combs
TL;DR: In this paper, the authors proposed a scheme for multi-band microwave sources generation based on dual optical frequency combs (OFCs) by optically channelizing the mixed OFCs, the heterodyned electrical signals in different bands can be obtained in different channels.
