Abstract
PURPOSE: To diffract the light beam entered by the sound waves reflected by a curved face and perform ultrasonic light modulation of high efficiency at a high speed by forming another face of an acousto-optic medium provided with a transverse wave piezoelectric converter on one face to a curved face which reflects sound waves.
CONSTITUTION: Since the ridge assumed by another face 7 differing from the face 6 of an acousto-optic medium 1 provided with a piezoelectric converter 2 and the face 8 orthogonal with this is polished to a radius R of curvature, the transverse sound waves emitted from the piezoelectric converter 2 have their wave face advancing direction bent by 90° by a curved face 9 and intersect nearly at a light angle with incident light 3. At this time, the sound waves are converted not to flat face but to the wave face having curvature by the curved face; therefore, the angle components that the sound waves possess spreads and this makes it possible to satisfy Bragg's conditions over the entire angle component of the incident light 3 entering by being focused, thus an ultrasonic light modulator of a high speed and an optical fiber switch of low crosstalk may be formed.
