A Compact and High-Q value SiN Microring Resonator for Microwave Photonic Applications

We have explored compact design of microring resonator in SiN platform for a demonstration of widely tunable narrow-bandpass microwave photonic filter and optoelectronic oscillator. Higher Q value (> 10 ⁶ ) and wider FSR (> 100 GHz) of a microring resonator are the essential figure of merits for such applications.
