Abstract
Wavelength division multiplexing (WDM) is one of the most promising approaches for increasing transmission capacity in an optical communication system.1 The integrated-optic technique makes it possible to produce stable reliable optical devices for use in single-mode transmission systems. Here we describe a new WDM system using a monolithically integrated multiwavelength GaInAsP/InP laser array with 50-Å wavelength separation2 and an integrated-optic multi/demultiplexer employing the waveguide technique.
