Paper Abstract

Ti-Au and annealed Ti-Pt-Au p-type contacts are demonstrated to improve the adhesion over a pure gold contact and allow annealing of the metallization to thin p-cladding laser structures at the expense of an increase in the optical loss. As little as 10 angstroms of titanium is adequate for an adhesion layer and only increases the optical loss by 1.6 cm-1 over a pure gold metallization which has an optical loss of 10.0 cm-1. A metallization of 15 angstroms Ti - 15 angstroms Pt - 1500 angstroms Au is adequate for an anneal at 410 degree(s)C for 10 sec and increases the optical loss by 7.0 cm-1.
