摘要： A photo-pickup wherein a light emitting portion, a surface acoustic wave generating portion, a lens portion, a light receiving portion and a control portion are integrally integrated on a base plate formed on its surface with a light transmission path. The light emitting portion propagates a light beam to the light transmission path. The light beam propagating in the light transmission path is first deflected within a plane of the light transmission path by surface acoustic wave propagating on the light transmission path and propagated towards the lens portion. The lens portion is provided to project the light beram outside from the light transmission path and effect two-dimentional focusing of the projected beam and adjustment of focal position. The light receiving portion comprises a combination of a plurality of light receiving elements disposed at suitable intervals from the projected position of the light beam to receive a reflected light of the light beam. The control portion is provided to receive an output of the light receiving portion to process a signal and supply said control signal to the surface acoustic wave generating portion and lens portion, thereby effecting the control of deflection angle of the light beam, two-dimentional focusing of the projected beam and control of focal position.

摘要： An optical comparator for comparing, bit by bit, corresponding bits of two optical digital signals which are identical in the number of constituent optical bit signals, includes an optical waveguide layer made of an acousto-optical material. A surface acoustic wave generator generates a surface acoustic wave propagating on the waveguide layer, and a photocoupler directs the constituent bit signals to be of the two optical digital signals incident on the waveguide layer so as to satisfy the Bragg diffraction condition with respect to the surface acoustic wave propagating on the waveguide layer. A photosensor detects diffracted light and/or undiffracted light which has passed through a surface acoustic wave interaction region. The position of the generator and/or the surface acoustic wave generating timing is so determined that initiation or cessation of the interaction of the surface acoustic wave with a bit of one of the optical digital signals is simultaneous with initiation or cessation of the wave interaction with a corresponding bit of the other optical bit signal.

摘要： By an electro-optical switch or an optical switch element utilizing diffraction by a surface acoustic wave, an input light beam is first switched over to one of light beams two or a multiple of two in number and propagating in different directions. By a surface acoustic wave which is discretely variable in frequency, the light beam in each of the different propagation direction is deflected at angles in accordance with the varying frequencies while propagating through an optical waveguide layer. It is possible to obtain by switching a very large total number of output light beams which are equal in number to the number of resolvable deflected light beams obtained in the frequency bandwidth of one surface acoustic wave, multiplied by the number of light beams obtained by switching with the optical switch element.

摘要： A tunable semiconductor laser has an active layer, an insulating film made of a piezoelectric material and formed on a portion of the active layer, and an interdigital transducer provided on the insulating film for generating a surface acoustic wave. The laser oscillation wavelength is variable by varying the wavelength of the surface acoustic wave generated by the transducer. When adapted to produce surface acoustic waves of different frequencies at different locations, the transducer affords an enlarged tunable wavelength band. A plurality of Gunn diodes effecting oscillation at different frequencies are usable in place of the transducer.
