Abstract:
1. A laser mux assembly comprising: an optical multiplexer including a plurality of input ports and an output port, the optical multiplexer being configured to filter light received on each of the input ports at different respective channel wavelengths for each of the input ports and to provide the filtered light to the output port; a laser emitter including a gain region for emitting light across a range of wavelengths including a plurality of channel wavelengths, the laser emitter coupled to the output port such that the emitted light is coupled into the output port and passes to the input ports; a front reflector configured to reflect at least a portion of light from the gain region of the laser emitter back to the output port of the optical multiplexer; and at least one back reflector selectively coupled to a selected one of the input ports, wherein the back reflector is configured to selectively reflect the filtered light from the selected one of the input ports back to the gain region in the laser emitter such that a lasing cavity is formed between the back reflector and the front reflector and within the optical multiplexer and lasing occurs at the channel wavelength reflected through the optical multiplexer back to the gain region of the laser emitter, and wherein the optical multiplexer, the front reflector and the at least one back reflector are configured to form a plurality of selectable lasing cavities for lasing at the different respective channel wavelengths; wherein the front reflector includes a partial reflector on a front side of the laser emitter, and wherein the laser emitter is anti-reflective on a back side optically coupled to the output port.
