Low power and compact eight-channel reconfigurable optical add-drop multiplexers based on cascaded microring resonators

Abstract

We report an eight-channel reconfigurable optical add-drop multiplexers (ROADMs) based on cascaded microring resonators with low tuning power and compact footprint. Microheaters are fabricated on the top of microring resonators, which can modulate microring resonators by the thermo-optic effect to achieve the reconfigurable functionality of the device. We… (More)
