ABSTRACT:
A waveguide type optical device connected with optical fibers and electronic wires, for converting an optical signal to an electronic signal vice versa, including a chip housing body housing an optical waveguide chip, a light emitting and detecting device assembly fitted to one side wall of the chip housing body and including both light emitting element and light detecting element precisely arranged so that the light emitting and detecting device assembly is fitted to the chip housing body by simple optical adjustment performed between waveguide terminal of the waveguide chip and the light emitting, detecting elements respectively. The chip housing body has structure so that the light emitting and detecting device assembly is the one side wall of the chip housing body and the optical fibers are connected with the waveguide chip through other side wall opposite to the one side wall, by applying a folded waveguide to the waveguide chip.
