| An opportunity for exploiting specific mechanism of the acousto-optic nonlinearity to regulate performances of the collinear acousto-optical filter, realizing the sequential spectrum analysis of optical signals, is considered. This possibility is theoretically analyzed and confirmed experimentally with an advanced filter based on calcium molybdate (CaMoO4 ) single-crystal with a 15 microsecond time-aperture. It is able to operate over red and nearinfrared light at relatively low radio-wave frequencies providing almost lossless regime for the controlling acoustic waves of the finite amplitude. Under certain conditions, the transmission function of electronically tunable filter exhibits a marked dependence on the applied acoustic power density, and as a result, one can significantly squeeze the transmission function, i.e. in fact improve the spectral resolution of this filter at the cost of decreasing the device efficiency partially. The identified and observed non-linear effect makes possible varying the performance data of similar advanced collinear acousto-optical filter governed by external signals of the finite amplitude. | |
