Paper Abstract

The microwave phase shifter using 25-GHz dense wavelength division multiplexing (DWDM) channel spacing tuning on the silicon-on-insulator microring resonator (MRR), which was utilizing the multimode interference as the coupling function to achieve wavelength independence, is proposed and demonstrated. With a quality factor of 1199 for the MRR, there was 25-deg phase tuning for every 25-GHz DWDM channel spacing at 5-GHz microwave frequency. The total tunability from the microwave phase shifter could achieve 350 deg using 22 DWDM channels with 25-GHz spacing.
