Method for connecting optical waveguide and optical fiber, semiconductor optical device, and method for manufacturing semiconductor optical device to which optical fiber is connected

摘要

It is possible to suppress the optical loss related to the conversion of the mode field diameter and to suppress the deformation of the mode field converter. Temporary fixing step of temporarily fixing the end surface of the optical fiber (1) to the end surface of the core portion (8) through the highly adhesive resin (3), and after the temporary fixing step, the end surface of the core portion (8) is high Fixing the optical fiber (1) to the semiconductor optical device (100) at a position away from the end face of the optical fiber (1) while abutting the end face of the optical fiber (1) through the adhesive resin (3).
