Abstract:
1. An optical assembly comprising: a crystalline substrate having a top planar surface and a crystalline plane angle; at least one groove defined in said top planar surface and having side walls extending from an edge of said substrate to a terminal end, said groove having a first facet at said terminal, said first facet having a first angle relative to said top planar surface, said first facet being reflective; an optical conduit having an optical axis and an end face optically coupled with said first facet; a waveguide; an optical component having a bottom surface; and a diffractive optical element (DOE) disposed on said bottom surface of said optical component such that said DOE is disposed above said first facet and configured to couple light between said waveguide and said optical conduit as reflected by said first facet.
