Claim Text:
1. A multi-wavelength laser, comprising: a shared reflector; a plurality of single-channel reflectors; a plurality of single-channel filters, each single-channel filter being configured to direct light at a respective wavelength from the shared reflector to a respective single-channel reflector and from the respective single-channel reflector to the shared reflector, wherein light at the respective wavelength propagates along a respective single-channel optical path between the respective single-channel filter and the respective single-channel reflector and a shared optical path between the respective single-channel filter and the shared reflector, wherein the single-channel optical paths and the shared optical path, together, define a multi-wavelength laser cavity extending from the shared reflector to the plurality of single-channel reflectors; and a shared filter positioned in the shared optical path and configured to select a subset of a plurality of cavity modes for the multi-wavelength laser cavity.
