Paper Abstract

In this talk, we propose a novel tunable optical add/drop multiplexer (OADM), based on Asymmetric Bragg Coupler (ABC) and the liquid crystal as the active layer material. The asymmetric Bragg coupler is made of OG series polymer ridged waveguide. The liquid crystal is filled to cover the waveguide structure, which sandwiches between upper and bottom electrodes. When the external voltage applied, the index of liquid crystal changes to adjust effective index of coupler and inherently tunes the transmission spectrum of the device precisely. The transmission bandwidth is about 32.5GHz, and the tunable range is about 250GHz centered at 1.55nm.
