Photodiodes developed in the GaSb-InAs system were first used for investigation the spectral characteristics of single and coupled disk lasers emitting on whispering gallery modes at 2.2–2.3 µm. The capacity of the photodiodes with a diameter of photosensitive area of 2.0 mm was C=520 pF at U=−2 V, which corresponds to a time constant of tau=53 ns. It is shown that the parameters of the developed photodiodes make it possible to detect the emission of quantum-sized disk lasers at room temperature and not to use cryogenic cooling.
