    Abstract: A planar lightwave circuit (PLC) module (1220) for conditioning output from a tunable laser (1210) designed to generate light at a target wavelength. The PLC module (1220) has a substrate; a primary waveguide (1221) embedded in said substrate, said primary waveguide (1221) having an input end for receiving light from the tunable laser (1210) and an output end for outputting said light; and at least a first secondary waveguide (1223) embedded in said substrate, said first secondary waveguide (1223) receiving a first portion of said light from said tunable laser (1210). A filter (1227) having a pass band centered on the target wavelength is coupled to an output of the sirst secondary waveguide (1223) to receive said first portion of light, and generates a signal related to the intensity of said first portion of ligth in the pass band centered on the target wavelength. This may be used by a processor (1230) and associated laser control circuitry (1232) for wavelength locking purposes.
