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.
