Abstract
Official abstract text for this publication.
A laser array mux assembly generally includes an array of laser emitters coupled to an optical multiplexer, such as an arrayed waveguide grating (AWG), with an external partial reflector after the multiplexer. Each of the laser emitters may include a gain region that emits light across a range of wavelengths including, for example, channel wavelengths in an optical communication system. The AWG filters the emitted light from each of the laser emitters at different channel wavelengths associated with each of the laser emitters. The reflector reflects at least a portion of the filtered light such that lasing occurs at the channel wavelengths of the reflected light. The laser array mux assembly may be used to generate an optical signal at a selected channel wavelength or to generate and combine optical signals at multiple channel wavelengths.
First claim
Opening claim text (preview).
What is claimed is: 1. A laser array mux assembly comprising: an array of laser emitters, each of the laser emitters including a gain region for emitting light across a range of wavelengths including a plurality of channel wavelengths and a back reflector for reflecting light from the laser emitters, wherein the back reflector of each of the laser emitters is highly reflective, and wherein each of the laser emitters includes an anti-reflective coating on an opposite side, the anti…
