Article Description

We report the high temperature operation of 1.3 μm ridge waveguide Fabry-Perot lasers utilizing a double-carrier-confinement heterostructure, with an active region containing an n-type lattice-matched multiple quantum well (MQW) as well as a p-type strained MQW. All devices with a cavity length of 400-1000 μm and as-cleaved uncoated facets operated beyond 100°C in the cw mode with an optical power in excess of 8 mW. T was found to be in the range of 65-75 and 72-98 K, for uncoated devices and devices with one high-reflectivity-coated facet, respectively.
