Abstract :
The paper presents the architecture of an acousto-optic tunable filter (AOTF) close-to-collinear interaction, in order to improved performances in terms of crosstalk and selectivity: the FWHM (Full width at half maximum) is decreased and the side lobe level is reduced. This filter architecture is based on a double-pass of the optical wave in the crystal and takes advantage of the anisotropic interaction.
