Abstract
There has been an increased interest in infrared gas sensing using novel LEDs and diode lasers emitting in the mid-IR spectral range. Such sources are especially attractive for fibre optic applications and spectrometers because of small size and high efficiency in the spectral range where most of industrial gases have characteristic absorption bands. For that reason of interest are new light modulators which can be coupled with the above sources operating at CW or pulse mode. The report presents data on new acoustooptic modulator based on amorphous Si-Te alloy and utilized in fibre optic hydrocarbons sensor based on InGaAsSb/InAsSbP diode laser emitting at 3.3 µm.
