Abstract: This paper describes work in the area of hybridization of optoelectronic devices and passive optical waveguide elements. The potential coupling efficiency of a laser diode to silica waveguides and fibers was improved by waveguide engineering. These diodes displayed far field angels of 16.5 degrees in the transverse direction. Strategies for passively aligning the didoes to planar silica waveguides on silicon substrates are also presented. !8
