Micro-ring resonator quality factor and extinction ratio enhancement via integrated Fabry-Perot cavity

摘要

We propose and experimentally demonstrate the enhancement of filtering quality factor (Q) and extinction ratio (ER) of an integrated micro-ring resonator through the use of an integrated Fabry-Perot cavity. Up to 11-times improvement in Q, together with an 8-dB increase in ER, are experimentally achieved.
