High-power output over 200 mW of 1. 3. mu. m GaInAsP VIPS lasers

Journal Article · · IEEE J. Quant. Electron.; (United States)
Maximum CW output power was investigated in GaInAsP 1.3 ..mu..m V-grooved inner stripe on P-substrate (VIPS) lasers considering both cavity length and facet reflectivity. Long-cavity lasers show a strong dependence of maximum output power on front reflectivity. A CW light output over 200 mW was obtained at room temperature using a 700 ..mu..m long cavity laser with 5 and 98 percent reflectivity of the front and rear facets, respectively. The fundamental transverse mode operation was confirmed up to 170 mW. A coupled power over 110 mW into a single-mode fiber was achieved with a coupling efficiency of 58 percent. The authors have verified the high reliability under high power levels, as high as 75 percent of the maximum CW output powers at room temperature.
