Paper Abstract

InAs, InSb compounds and InAs(Sb)(P), In(Ga)As(Sb) based heterostructures grown onto InAs substrate have been used as a 'phosphor' for the optically pumped light emitting diodes emitting in the mid-IR spectral range (3 divided by 7 micrometer) at room and above room temperatures. The pulse output of the LEDs composed of GaAs pumping LED ((eta) ext equals 6 divided by 8%) and 2 divided by 20 micrometer thick mid-IR 'phosphor' joint together through a transparent 'glue' was as high as 40 divided by 500 (mu) W which is fairy close to the best reported values for 'cascade' and single quantum well diodes operating in a spontaneous mode.
