Diffraction of light by acoustic waves on a membrane.
The diffraction of light by acoustic waves on a membrane is reported. A device can be made to perform acousto-optic signal processing at much lower frequencies than can be handled by the standard Bragg acousto-optic cell. Acoustic waveguiding phenomena are demonstrated. The device can handle simultaneous parallel-array data processing.
