Abstract

Lasing from HgCdTe microdisk cavities is demonstrated at wavelengths as long as 20–25 μm. The optical threshold and operation temperature are mainly limited by nonradiative Shockley–Read–Hall type recombination. The employed ion etching technology appears to introduce additional defects in the vicinity of the microdisks, degrading figures of merit as the height of the cavity increases. However, a watt-level mid-infrared pumping source should suffice for lasing in microdisks with a height of ∼3 and ∼100 μm diameter.
