Chuyển mạch quang lựa chọn bước sóng sử dụng bộ vi cộng hưởng ring và thiết bị giao thoa đa mode 3x3 mmi

Tóm tắt

A wavelength selective optical switch is developed based on a microring resonator using3 x 3 multimode interference (MMI) couplers in this paper. The device was designed using asilicon-an-insulator (SOl) single-mode rib waveguide. The switching function can be achievedby using the thermo-optic effect making use of the large thermo-optic coefficient of silicon. Avery high performance of the switch with a low switching power and fast response can beobtained by using this structure.
