Abstract:
An opto-electronic device, comprising:a miniature optical bench, said optical bench of a material with a relatively low coefficient of thermal conductivity; anda gain module rigidly coupled to and substantially thermally isolated from said optical bench, said gain module comprising:a monolithic substrate, wherein a plurality of registration structures are integral to a first surface of said substrate;a semiconductor pump laser coupled to said substrate and located in a first position with respect to said substrate, said first position defined by a first portion of said plurality of registration structures;a gain medium coupled to said substrate and located in a second position with respect to said substrate, said second position defined by a second portion of said plurality of registration structures, wherein an emission from said pump laser impinges on a surface of said gain medium;an optical element coupled to said substrate and located in a third position with respect to said substrate, said third position defined by a third portion of said plurality of registration structures, wherein said third position is interposed between said first position and said second position, and wherein said pump laser emission passes through said optical element prior to impinging on said surface of said gain medium; anda heat spreader coupled to a second surface of said substrate, said second surface on an opposite side from said first surface.
