Widely tunable dual loop optoelectronic oscillator based on a single-bandpass microwave photonic filter and a recirculating delay line

A wideband tunable dual loop Optoelectronic Oscillator based on a single-bandpass microwave photonic filter and a recirculating delay line is proposed and experimentally demonstrated. A tunable frequency range from 10.23 to 26.69 GHz is obtained. ? OSA 2014.EI
