ABSTRACT:
A method and apparatus are disclosed for an integrated photonic device. A transparent non-imaging optical director having a top and a bottom surface is integrated, at its bottom surface, with a photonic device. The bottom surface is approximately equal in area to the active area of the photonic device. The top surface of the director is larger than its bottom surface. The top and bottom surface are connected by a waveguiding region. The geometry and refractive index of the non-imaging optical director are controlled so that the light entering the director is preferably totally internally reflected. Substantially all optical energy of an optical signal received at the top surface of the non-imaging optical director will be directed to its bottom surface, and then to the integrated photonic device. Where the photonic device is an optical source, substantially all optical energy emitted that is received by the bottom surface is directed to the top surface.
