Abstract

Using interferometric couplers and thermal tuning, we demonstrate a novel design of compact microring resonators on silicon-on-insulator platform with tunable bandwidth from 0.1to0.7nm. The structures present an extinction ratio higher than 23dB and a footprint of less than 0.001mm2, which are suitable for integrated optical signal processing such as reconfigurable filtering and routing.
