In this paper tunable RF optoelectronic oscillator based upon direct modulation of laser diode and an optical fiber RF filter is demonstrated using the dc driving current of the laser diode. The use of the optical fiber RF filter allows a sidemode suppression ratio of 30 dB at discrete oscillation frequencies with frequency step equals to the intrinsic(More)
A novel optical technique is proposed for the characterization of MEMS resonators. The proposed technique is based on measuring the response of the resonator (resonance frequency and quality factor) optically, which eliminates the electrical parasitic effects. The proposed technique was applied to a comb-drive resonator and the obtained results show good(More)
