Title: Optically pumped Pb/sub 1-x/Sn/sub x/Se/sub 1-y/Te/sub y/ heterojunction lasers with matched gratings at the interface

Abstract

An investigation was made of the photoluminescence emitted from epitaxial films of Pb/sub 1-x/Sn/sub x/Se/sub 1-y/Te/sub y/ solid solutions (0< or =x< or approx. =0.47, 0< or =y< or approx. =0.65), grown by the method of liquid epitaxy on n-type PbSe substrates. Next, n-Pb/sub 1-x/Sn/sub x/Se/sub 1-y/Te/sub y//n-PbSe heterostructures, with the Pb/sub 1-x/Sn/sub x/Se/sub 1-y/Te/sub y/ active layer (0.015< or =x< or =0.092, 0.006< or =y< or =0.026), were matched in respect of the lattice constant to the substrate (..delta..a/aapprox. =10/sup -1/-10/sup -3/%) and used as optically excited heterolasers. The spectral and threshold characteristics were determined as a function of the thickness of the active layer d, temperature, and resonator length. Variation of the composition of the active layer altered the emission wavelength within the range 8-12.5 ..mu.. at 77/sup 0/K. Electron and optical confinement effects were observed when the thickness d was reduced. For the optimal thickness d/sub opt/approx. =/cm/sup 2/ at 77 /sup 0/K. The loss factor (5.5 cm/sup -1/), gain (0.11 cm/W), and carrier density (2 x 10/sup 17/ cm/sup -3/) in the active layer were determined.
