英文摘要 | PURPOSE:To lessen the coupling loss with optical fibers in a distribution feedback type semiconductor laser by a method wherein the laser is made into a structure, wherein the divergence angle of beams is smaller and the outgoing beam mode is brought nearer to a circular one. CONSTITUTION:A layered formation; which consists of a P type contact layer 2, P type antimeltback layer 3, and active layer 4, an N type waveguide layer 5 and an N type substrate 6; is formed, and N type buried layers 8 and P type buried layers 9 are formed on both sides thereof. After these layers are formed, the top surface of the P type contact layer 2 is masked with a resist, etc., leaving the wedge-shaped open part intact, and an almost conical cavity is formed by performing an etching for forming the cavity by epitaxially growing a buried and enlarged waveguide path 10. Lastly, a P-side electrode 1 and an N-side electrode 7 are respectively formed on the top surface and the bottom surface. The front 11 of the buried and enlarged waveguide path 10 is an outgoing end. |
