Abstract:
A surface semiconductor laser, comprising:a surface emitting semiconductor laser body, including: an active layer;top and bottom spacer layers sandwiching said active layer; andtop and bottom multilayer reflection films sandwiching said top and bottom spacer layers;a conductive bottom contact layer having a flat area larger than the flat area of said body, wherein said body is fromed on said bottom contact layer;an insulating substrate on which a plurality of units are arranged in the form of a matrix, each unit of said plurality of units including said body and said bottom contact layer;a bottom metal electrode extending continuously in one direction of said matrix beside each said body on the top surface of the bottom contact layer of each of said plurality of units arranged in parallel in the one direction of said matrix; andtop metal electrodes extending in another direction of said matrix on each of said plurality of units arranged in parallel in the other direction of said matrix.
