Abstract :
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 of feedback driving signal at fundamental frequency by converting the phase-modulated signal to intensity-modulated signal. As a result, a self-oscillating fundamental microwave signal at 8 GHz and frequency-doubled microwave signal at 16 GHz are simultaneously obtained.
