Paper Abstract

Internal quantum efficiencies of Pb Sn Te lasers with double-hetero geometries have been estimated. The efficiencies of conventional PbTe/PbSnTe/PbTe lasers are very low and far from the efficiencies which are limited by Auger-recombination mechanism. The main cause of low efficiency is thought to be due to the misfit dislocations at the PbTe-PbSnTe hetero-interface. To reduce the misfit dislocations, lattice-matched PbTeSe/PbSnTe/PbTeSe lasers are prepared and they show considerable improvements. However, due to the difficulty of cleaving of PbTeSe layers, the efficiencies are not sufficient. By designing a one-side-lattice-matched PbTeSe/PbSnTe/PbTe structure, the lasers whose efficiencies are very close to the theoretical limit can be prepared.
