Abstract:

GaAs-based semiconductor lasers with emission wavelengths around 626 nm, 725 nm and 1180 nm are challenging due to the necessary strain in the quantum well region. However, there is a lively interest worldwide in tapping into these wavelength ranges with semiconductor lasers. Here we describe the fabrication and properties of both broad area and ridge waveguide semiconductor lasers emitting at 626 nm, 725 nm and 1180 nm. For that, GaAs-based laser structures with highly strained quantum wells have been developed.
