Abstract

Modulator base don the amorphous Si-Te acousto-optic cell and operating in the mid-IR region has been manufactured and tested using 3.3 micrometers diode laser based on InGaAsSb/InAsSbP double heterostructure. Amplitude modulation efficiency for the laser beam coming from the end of a As₂S₃ fiber appeared to be not less than 70 percent, allowing to use the cell in optical gas sensor applications.
