Paper Abstract

A wideband and frequency-tunable optoelectronic oscillator implemented by employing a two-port optical phase modulator and a phase-shifted fiber Bragg grating without using electrical microwave filters is proposed and experimentally demonstrated. The key device is the phase-shifted fiber Bragg grating, which functions, in conjunction with the phase modulator in the loop, to form a tunable high-Q microwave bandpass filter to perform frequency selection. The central frequency of the microwave photonic filter can be tuned by tuning the wavelength of the incident light wave; therefore, the oscillation frequency can also be continuously tuned. An experiment is performed. The generation of a microwave signal with a frequency that is tunable from 6 to 14 GHz is demonstrated.
