A simple realization of frequency-doubling optoelectronic oscillator (OEO) using a phase modulator and a chirp fiber Bragg grating (CFBG) is proposed and experimentally demonstrated. In this OEO configuration, the phase modulator in combination with an optical filter is working as doubled-sideband phase modulation to produce a frequency-doubling microwave signal, while the CFBG ensures the oscillation...
A wideband frequency-tunable optoelectronic oscillator (OEO) based on a narrowband phase-shifted fiber Bragg grating (PSFBG) and wavelength tuning of the laser is proposed and demonstrated. With assistance of an optical single-sideband modulator, the PSFBG with a narrow transmission peak acts like an equivalent high- microwave filter to select the oscillation frequency. Frequency tunability of...
