TL;DR: The proposed MWP SAR works perfect and shows the potential of overcoming the conventional radar bandwidth bottleneck, and is evaluated through a series of inverse SAR imaging tests.
Journal ArticleDOI
Photonic Time-Stretched Analog-to-Digital Converter Amenable to Continuous-Time Operation Based on Polarization Modulation With Balanced Detection Scheme
Jia Haur Wong,Huy Quoc Lam,Ruoming Li,Kenneth Eng Kian Lee,Vincent Wong,Peng Huei Lim,Sheel Aditya,Ping Shum,Sai Hua Xu,Kan Wu,Chunmei Ouyang +10 more
TL;DR: It is shown analytically and experimentally that a polarization modulator which supports TE and TM modes of opposite phase modulation indexes can be utilized to reject dispersion-induced even-order distortions in a photonic Time-Stretched Analog-to-Digital Converter (TS-ADC).
Journal ArticleDOI
Observation of timing jitter reduction induced by spectral filtering in a fiber laser mode locked with a carbon nanotube-based saturable absorber
Chunmei Ouyang,Ping Shum,Honghai Wang,Jia Haur Wong,Kan Wu,Songnian Fu,Ruoming Li,Edmund J. R. Kelleher,Alexander I. Chernov,Elena D. Obraztsova +9 more
TL;DR: A self-starting passively mode-locked fiber laser with a carbon nanotube-based saturable absorber and a fiber-based bandpass filter is proposed, leading to a great reduction of its timing jitter.
Journal ArticleDOI
Frequency tunable optoelectronic oscillator based on a directly modulated DFB semiconductor laser under optical injection.
Peng Wang,Jintian Xiong,Tingting Zhang,Dalei Chen,Peng Xiang,Jilin Zheng,Yunshan Zhang,Ruoming Li,Long Huang,Tao Pu,Xiangfei Chen +10 more
TL;DR: Through optical injection, the relaxation oscillation frequency of the DFB laser is enhanced and its high modulation efficiency can enable the loop oscillation with a RF threshold gain of less than 20 dB.
Journal ArticleDOI
Millimeter-Wave Vector Signal Generation Based on a Bi-Directional Use of a Polarization Modulator in a Sagnac Loop
TL;DR: In this article, a bi-directional use of a polarization modulator (PolM) in a Sagnac loop is proposed and experimentally demonstrated to generate a frequency-doubled millimeter-wave (mm-W) vector signal that is immune to fiber chromatic-dispersion-induced power fading and free from interband beating interferences.
