Infrared emission from the substrate of GaAs-based semiconductor lasers
Mathias Ziegler, Robert Pomraenke, Max Felger, Jens W. Tomm, Parinda Vasa et al.
We report on the origin of three additional low-energy spontaneously emitted bands in GaAs-based broad-area laser diodes. Spectrally and spatially resolved scanning optical microscopy and Fourier-transform infrared spectroscopy assign the different contributions to bandtail-related luminescence from ... [Appl. Phys. Lett. 93, 041101 (2008)] published Mon Jul 28, 2008.
