Semiconductor lasers and method for making the same |
摘要 |
A semiconductor laser diode, and a method for producing the semiconductor laser diode, includes a waveguide being terminated by a back facet and a front facet and a front facet coating and a back facet coating having a reflectivity providing for controlled decoupling of light at the front facet from the standing lightwave in the waveguide. The front facet coating includes a stack of layers providing for a phase shift of the standing lightwave within the waveguide such that the intensity of the lightwave at the front facet, where the light is decoupled from the standing lightwave, has a relative minimum.
