Optical Property of Electric Tuning Optical Add and Drop Multiplexer Based on SOI Waveguide

摘要

Dynamic optical add-drop multiplexer (OADM) is a key component in computer networks in the future. Also the optical add-drop multiplexer played an important role in enabling greater connectivity and flexibility in dense wavelength-division multiplexing (DWDM) computer backplane networks. Based our previous simulation works, we have fabricated the electric tuning optical add-drop multiplexer devices. Owing to the large index step difference between SiO_2 and Si, it permits good confinement of light and the size reducibility of using the SOI structure. Different from traditional tunable optical add-drop multiplexer, we design a tunable optical add-drop multiplexer which uses MMI structure based on SOI wafer. In this paper, we measure the optical properties of characteristics and ability of electric tuning OADM devices as well as discuss the difference between experimental and theoretical results.
