摘要: A plurality of modulating elements are provided on a substrate to modulate the intensity of input light in dependence upon an applied physical quantity. Intensity-modulated output optical signals from these plural modulating elements propagate in parallel along the substrate. These parallel optical signals are successively diffracted by a pulsed surface acoustic wave, and the diffracted light is then focused. Since parallel optical signals from a plurality of modulating elements can thus be converted into a serial optical signal, the signal can be transmitted by a single optical fiber.

摘要: A device for processing optical data comprising:
an optical waveguide formed on a substrate, a light source for the laser beam to be admitted into the waveguide, lens means provided on the waveguide for causing the beam propagating through the waveguide to emerge obliquely upward and focusing the emergent beam two-dimensionally, means for receiving the beam reflected obliquely from above, a base provided with the laser light source, the substrate and the light receiving means, a focusing drive mechanism for adjusting the position of the base upward or downward, and a tracking drive mechanism for adjusting the position of the base laterally.
