1. An optoreflective structure for reflecting an optical signal following a path defined by an optical waveguide comprising a first cladding layer having a first planar cladding surface;

  • a waveguide disposed on said first cladding layer;

    a second cladding layer disposed on said waveguide and having a second planar cladding surface;

    said first cladding layer, said second cladding layer and said waveguide terminating in a beveled planar surface; and

    an optoreflector disposed on said beveled planar surface for changing a direction of an optical signal passing through the waveguide.
