Efficient acousto-optical light modulation at the mid-infrared spectral range by planar semiconductor structures supporting guided modes
Ivan M. Sopko, Daria O. Ignatyeva, Grigory A. Knyazev +1
Acousto-optical devices, such as modulators, filters or deflectors, implement a simple and effective way of light modulation and signal processing techniques. However, their operat…
