A High-Frequency Acoustic Pulse Modulator-Splitter with Controllable Polarizations of the Output Channels

Аннотация

Abstract—A two-channel high-frequency acousto-optic (AO) modulator-splitter has been developed, which splits optical radiation into two equal optical channels and modulates the intensities of the output channels at double the sound frequency. The modulator makes it possible to simply change the polarization of the output beams. A model of a modulator made of a TeO₂ single crystal was used to modulate and split radiation with a wavelength of 0.63 × 10^–4 cm. Intensity modulation of the output channels at a frequency of ~200 MHz was achieved.
