Journal ArticleDOI
Broadband random optoelectronic oscillator.
TL;DR: This work combines the unique features of random scattering and OEO technologies by proposing an OEO structure based on random distributed feedback, and demonstrates the generation of ultra-wideband (up to 40 GHz from DC) random microwave signals in an open cavity OEO.
Journal ArticleDOI
Widely Tunable Single-Passband Microwave Photonic Filter Based on DFB-SOA-Assisted Optical Carrier Recovery
TL;DR: In this article, a widely tunable single-passband microwave photonic filter (MPF) based on a distributedfeedback semiconductor optical amplifier (DFB-SOA) is proposed and experimentally demonstrated.
Journal ArticleDOI

TL;DR: In this paper, a novel microwave photonics technique that enables the modulation of orthogonal optical single-sideband (OSSB) by using an improved Sagnac-loop-based modulator is proposed and experimentally demonstrated.
Journal ArticleDOI
Two-port calibration of test fixtures with different test ports
TL;DR: In this paper, the problem of phase uncertainty arising in this application has been solved, and the comparison between the results and those obtained with the SOLT method shows that the method established is accurate for practical applications.
Journal ArticleDOI
Measurement of Chirp Parameter and Modulation Index of a Semiconductor Laser Based on Optical Spectrum Analysis
TL;DR: In this article, a simple method for measuring the chirp parameter, frequency, and intensity modulation indexes of directly modulated lasers is proposed in a small-signal modulation scheme.
