Abstract
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.
