Claim:
1. A method of fabricating a packaged photonic device, comprising: forming on a top surface of a substrate a semiconductor structure comprising an active layer; etching at least one facet in said semiconductor structure defining at least one side surface of said semiconductor structure and at least one side wall in said semiconductor structure defining remaining side surfaces of said semiconductor structure, wherein said etching exposes said active layer; directly covering all side and top surfaces of said semiconductor structure with a single continuous protective layer of a dielectric material including directly covering said active layer at said at least one etched facet; forming an electrically conductive contact in a contact window formed in said single continuous protective layer on a top surface of said semiconductor structure with a metal layer overlapping said single continuous protective layer outside said contact window; singulating said substrate comprising said semiconductor structure to form a photonic device; and packaging said photonic device in a non-hermetic package; wherein all side and top surfaces of said semiconductor structure remain directly covered with said single continuous protective layer and said metal layer to seal said semiconductor structure when said photonic device is packaged in said non-hermetic package.
