Abstract:
1. An apparatus comprising: a support substrate having a top surface; a waveguide suitable for transmitting light, the waveguide being formed embedded within the support substrate and having a waveguide thickness that is measured in the orthogonal direction from the top surface of the support substrate; an optical lens that is integrally formed with the waveguide, the optical lens having an inclined back surface that has a first edge that joins the waveguide and a second edge that extends to the height of a maximum lens thickness of the optical lens and having a maximum lens thickness that is greater than the waveguide thickness, wherein light rays transmitted from the waveguide are collimated by the optical lens so that the light rays are emitted out of the optical lens in a plane that is substantially coplanar to the top surface of the support substrate; and a cladding material layer that lies in contact with and underneath a bottom surface of the waveguide and in contact with and underneath a bottom surface of the integrally formed optical lens.
