Paper Abstract

We report about light-emitting diodes (LEDs) and photodiodes (PDs) for the spectral ranges 1.8 - 2.4 micrometer and 2.9 - 4.7 micrometer based on multicomponent III-V alloys (GaInAsSb/GaAlAsSb, InAsSb/InAsSbP). High-efficiency small-dimension optoelectronic devices were applied to the design of novel set gas and moisture analyzers. Progress in development of different kinds of experimental models of the analyzers is demonstrated. Such portable sensors can be used for ecological monitoring, detecting industrial pollutants, and for various medical applications.
