Abstract

Planar lightwave circuits (PLCs) are circuits that integrate fiber-matched optical waveguides on Silicon substrate to provide an efficient means of interaction for the guided-wave optical signals[1]. This paper describes the recent progress in PLCs such as star couplers, arrayed-waveguide grating WDM/FDM circuits, transversal filters, and polymer and Er-doped waveguides for possible active devices.
