ABSTRACT:
A planar lightwave circuit is provided that includes a substrate and at least one boundary positioned in the substrate and defining a cavity. The boundary is substantially non-transmissive and absorbing for wavelengths of stray light present in the vicinity of the boundary. The boundary possesses substantial symmetry under at least one symmetry group operation.
