Abstract

A reflector chip of the present invention integrates a planar lightwave circuit (PLC) waveguide wafer and an active component, such as a photo-detector or laser, e.g. vertical cavity surface emitting laser. Typically, the PLC waveguide wafer includes a waveguide core region bound by upper and lower cladding layers. An end of the waveguide core region is mounted within a channel, trench, notch or recess within the bottom surface of the body of the reflector chip. A V-notch is also formed in the bottom surface of the body of the reflector, including a reflective surface, which redirects the light between the active component and the waveguide core region.
