METHOD FOR CONNECTING OPTICAL WAVEGUIDE AND OPTICAL FIBER, SEMICONDUCTOR OPTICAL DEVICE, AND METHOD FOR MANUFACTURING SEMICONDUCTOR OPTICAL DEVICE HAVING OPTICAL FIBER CONNECTED THERETO
The present invention makes it possible to prevent an optical loss in association with mode field diameter conversion and to prevent deformation in a mode field converter. The present invention includes: (a) temporarily fixing an end surface of an optical fiber (1) to an end surface of a core part (8) via a highly-viscous resin (3); and (b) after the step (a), while butting the end surface of the optical fiber (1) against the end surface of the core part (8) through the highly-viscous resin (3), fixing the optical fiber (1) to a semiconductor optical device (100) at a place away from the end surface of the optical fiber (1).
