Abstract
An active monolithic optical device for wavelength division multiplexing (WDM) incorporating diode laser arrays, an output coupling waveguide and a curved Rowland circle based grating to produce a plurality of individual laser beams at slightly different wavelengths is integrated in a common electro-optic material. The wavelength of each laser source is determined by the geometry of the array and the diffraction grating design. The output of all the channels can be collected into a concentrator or lens to be multiplexed in a single output. Applications include a WDM optical amplifier and WDM laser source.
