Abstract

PURPOSE:To attain the direct conversion for the optical data of the parallel input into a serial optical data, by setting an ultrasonic wave oscillator IDT on the waveguide layer on the surface of a piezoelectric substrate and carrying out a selective Bragg diffraction through the IDT and the parallel optical data. CONSTITUTION:The signal to drive IDT3 and 4 is transmitted from a driving circuit 13 via a lead wire 14, and at the same time the pulse type start signal is applied to an LD15 via a lead wire 16. As a result, the light emitted from the LD15 is directly made incident to a grating lens 9. Then the parallel optical data supplied to beams P1-Pn is extracted only by one unit by propagating beams 5 and 6 of the IDT3 and 4. These extracted beams Q1-Qn can be extracted in the form of serial signals out of a fiber connector 11 via lenses 9 and 10. In such way, the optical data which is supplied in parallel can be converted directly into a serial optical data without converting it into the electric signal.
