High-power light-emitting diodes operating at 4.6 µm with potential for use in an optical carbon monoxide sensor have been fabricated by liquid phase epitaxy (LPE) with a pulsed output power in excess of 1 mW at room temperature. The InAs0.89Sb0.11 in the LED active region was purified using rare earth ion gettering of the growth solution during epitaxy.
