ABSTRACT:
The multi-channel optical device includes a demultiplexer in a laser cavity. The demultiplexer is configured to demultiplex a multi-channel light beam into a plurality of channels. The device also includes a plurality of ports. Each channel exits the laser cavity through a different one of the ports.
