Title: Planar lightwave circuit package

Abstract: An optical packaging arrangement combines a planar lightwave circuit (PLC)having an array of waveguides thereon, an array of photodetectors on asubstrate to receive light beams coupled out of the PLC by the outputports, and a collimating faceplate, having a plurality of glass cores,extending between the PLC and the photodetector array for coupling theoutput light beams to respective photodetectors. The faceplate forms acover for a hermetic cavity encompassing the photodetectors. The PLC isdisposed either co-planarly with the faceplate or transversely to it.Light from the PLC is tapped via a plurality of taps formed on the PLC forcoupling to the photodetectors.
