Superluminescence from optically pumped CdxHg1-xTe heterostructures on GaAs and Si substrates
We report the experimental observation of superluminescence in the wavelength range 1 .4 - 4.5 μm from epitaxial structures Cdx4Hg1-xTe under pulsed optical pumping by Nd:YAG laser. The samples CdxHg1-xTe were grown on GaAs and Si substrates by the Molecular Beam Epitaxy. The stimulated emission has been observed from the structures at temperatures 77 - 200 K. Details of the samples, observation scheme, the super luminescence spectra are discussed.
