Abstract

A compact microwave photonic filter (MPF) with continuous tunability of central frequency based on a microdisk (or cascaded microring) resonator on a single silicon-on-insulator (SOI) chip is proposed and experimentally demonstrated. Assisted by the optical single side-band (OSSB) modulation, the optical frequency responses of microring and microdisk resonators are mapping to the microwave frequency response to form an MPF whose central frequency is continuously tunable. Different SOI resonators, including two microdisk chips whose Q factors are 1.07×10⁵, 1.5×10⁴ and a cascaded microring chip whose Q factor is 2.9×10^4,are used to implement the MPFs. The performance of these MPFs is compared in terms of bandwidth, tuning range and rejection ratio. Our approach will allow the implementation of very compact, low-cost, low-consumption and integrated notch MPFs in a silicon chip.
