ABSTRACT:
A DWDM add/drop system for use in optical communication system is disclosed. Using semiconductor fabrication techniques, a plurality of waveguide arrays and signal carriers are substantially symmetrically arranged about an optical axis of the system. Electrode heaters are provided proximate junctions created at the intersections of selected waveguides. Using the heaters, portions of optical signals may be redirected to other waveguides. In addition, the heaters may be used to attenuate or otherwise modify signals in the waveguides. The waveguide arrays are arranged such that a plurality of signal processing operations may be performed substantially simultaneously. In a preferred embodiment, the switches and waveguide arrays are coupled with a light focusing device and a dispersion apparatus to form a switched, combined multiplexer/demultiplexer having signal attenuation and modification capabilities.
