High temperature operation of 1.3 μm ridge waveguide lasers using lattice matched and strained multiple quantum wells

Abstract

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. T0 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.
