Even if there is a temperature variation, a positional discrepancy at a colliding surface of an active surface of a semiconductor laser and an optical waveguide is suppressed, resulting in realization of a semiconductor light emitting element coupled with optical fiber of stable operation. In order to realize the above object, a semiconductor light emitting element coupled with optical fiber comprises a substrate, an optical waveguide disposed on the substrate and including a core and a cladding layer covering the core, a semiconductor light emitting element disposed on the substrate and comprising an output end-surface facing one end of the core of the optical waveguide, and an optical fiber comprising a core an end of which faces the other end of the core of the optical waveguide, wherein the cladding layer sandwiches both surfaces of the semiconductor light emitting element.

Semiconductor light emitting element coupled with optical fiber

To obtain an inexpensive, high-power optical fiber output semiconductor device, an edge emitting type semiconductor element, a tapered optical waveguide having a structure for accommodating expansion and contraction due to a change in temperature, and an optical fiber are prepared separately. One edge of the tapered optical waveguide is butt-joined to an output face of the edge emitting type semiconductor element. The other edge of the tapered optical waveguide is connected to the optical fiber.

Power supplies, a ground, and so forth of an analog portion including an image pickup portion,are connected to electrode pads,. Power supplies, a ground, and so forth of a digital portion are connected to electrode pads,. Thus, various problems such as an increase of impedance of power supplies and a ground, signal crosstalk between each circuit, and noise due to internal line connections between the image pickup portion,and a peripheral portion,can be prevented.

Photoelectric integrated circuit device

An adhesive agent 116 is coated to a peripheral flat portion 115 of an optical glass 113. A center flat portion 114 is mounted to an opening portion 108 of a TAB tape 105 from the reverse side of which copper leads 107 are formed. Thus, the optical glass 113 and the TAB tape 105 are adhered. At this point, the center flat portion 114 and the TAB tape 105 are arranged almost on the same plane. Thus, protrusion of the adhesive agent 116 and foreign matter stuck on the optical glass 113 can be easily and securely removed.
