Electro-optical and temperature tunable WDM filter

Abstract

We present a new concept of a tuneable WDM filter. With this device we demonstrate that tuning over the complete C or L band is feasible by using either Temperature or the Electro-Optic effect. We have simulated and designed a device in the InP-based material system with capacity for two channels spaced 15 nm. Design, simulation, and the preliminary experimental results are presented in this paper
