Abstract

The maturity of GaAs/AlAs-based technology enabled the fabrication of highly efficient diode lasers based on (AlGaIn)As/GaAs as well as (AlGa)As/GaAs active regions. Furthermore, these material systems have proven to be widely adaptable, because the GaAs/AlAs system allows for the fabrication of various cavity concepts including in-plane as well as vertically emitting laser structures and the emission wavelengths of the above-mentioned active regions can be tailored from the red to the near-infrared wavelength regime. However, the fabrication of GaAs-based telecommunication lasers proved to be difficult due to the high quality requirements in combination with strain-induced defect formation. While the demonstration of 1.3 μm lasers based on Ga(AsSb)/GaAs [1] as well as (GaIn)(NAs)/GaAs [2] was possible, (GaIn)(AsP)/InP and (AlGaIn)As/InP remained the dominant material systems for lasers emitting at wavelengths longer than 1.2 μm.
