PHOTOELECTRIC CONVERTING DEVICE, MANUFACTURING METHOD OF THE SAME, AND EXTERNAL WAVEGUIDE

摘要

A photoelectric converting device includes: an optical element that converts an electric signal to a light signal or a light signal to an electric signal; an IC circuit that sends the electric signal to the optical element or receives the electric signal from the optical element; a mount substrate having a waveguide that optically couples to the optical element; and an external waveguide that can be optically coupled to the waveguide. An optical connector is provided to the external waveguide at an end portion. The mount substrate is provided with a fitting portion that aligns the waveguide and the external waveguide with respect to each other as the optical connector fits therein.
