Method for reducing facet reflectivities of semiconductor light sources and device thereof |
| abstract |
METHOD FOR REDUCING FACET REFLECTIVITIES OF SEMICONDUCTOR LIGHT SOURCES AND DEVICE THEREOF ABSTRACT A novel method for reducing the facet reflectivities of semiconductor light sources and amplifiers concerns the use of a bulk (non-waveguiding) index-matched regrown end cap region at both of the major facet surfaces of the amplifier. The amplifier has a tilted stripe geometry which, in combination with the end cap regions, enable the amplifier to reproducibly achieve facet reflectivities of less than 10-5 while avoiding a facet coating step. The improved optical amplifier is more amenable to mass production and less sensitive to both wavelength and polarization. |
