Abstract:
An article comprising a surface plasmon laser structure comprisinga semiconducting substrate having a top major surface; an active region disposed to cover a portion of said semiconducting substrate top major surface, said active region formed as a ridge including sidewalls and a top surface; a metallic surface plasmon carrying layer disposed to cover a portion of said active region top surface; an insulating layer disposed to cover said active region sidewalls and exposed regions of said semiconducting substrate top major surface; and electrical contacts coupled to a bottom major surface of said semiconducting substrate to facilitate flowing an electrical current through the laser characterized in that the surface plasmon laser comprises a single mode device and the metallic surface plasmon carrying layer comprises a multiple layer metallic arrangement formed as a distributed feedback (DFB) grating arrangement exhibiting a periodic Bragg structure.
