Paper Abstract

Reconfigurable optical add/drop multiplexer (OADM), which is the fundamental element of wavelength division multiplexing (DWDM) system, employs various waveguide filter approaches. However, most of them are incapable of dropping more than a single channel at one time. Therefore, an electro-optically tunable reconfigurable OADM with Ti: LiNbO3 waveguide was designed and analyzed. The two electrodes layers, separated by silicon dioxide buffer, applied two orthogonal electrodes fields in the waveguides which induced the wavelength dependent polarization conversion and phase shifted respectively, and hence realized the add or drop function combining with two identical polarization beam splitter waveguides. Profiting from the two layered electrodes structure, the tuning range was enlarged twice as the original filter design. The multiple channels download is feasible due to the novel structure of the polarization conversion electrodes.
