Abstract
An express technique for characterizing narrow-gap waveguide heterostructures with the HgCdTe/CdHgTe quantum wells is proposed, which is based on an analysis of their room-temperature luminescence response. Advantages and constraints of this characterization technique are discussed in comparison with methods for more detailed diagnostics that entail photoluminescence and photoconductivity measurements in a wide temperature range.
