Abstract

Acousto-optic tunable filter (AOTF) is not obligatorily the better, the spectral selectivity is finer. It is often necessary to tune AOTF spectral transmission in accordance with certain problems. We have developed an APTF with variable parameters of spectral transmission. The device provides high values of partial diffraction efficiencies while simultaneous exiting of multiple acoustic waves with different frequencies. The wavelength selectivity varies from 5 through 30 nm, and its shape also varies from Gaussian to nearly rectangular. The results of this AOTF study have been listed and discussed. It has been shown that the specially developed software allowed changing the spectral transmission characteristics according to any given law. The possible areas of such device application have also been discussed.
