Abstract

Planar lightwave circuits (PLCs) provide various important devices for WDM systems, TDM systems, and subscriber networks. This article reviews the recent progress and future prospects of PLC technologies including arrayed-waveguide grating (AWG) wavelength filters, optical add/drop multiplexers (ADMs), programmable dispersion equalizers, and hybrid optoelectronics integration technologies. Continuous improvements in waveguide fabrication, circuit design, and device packaging will further bring these technologies to a higher level of integration of optics and electronics, aiming at the next generation of telecommunication systems
