Abstract: PROBLEM TO BE SOLVED: To provide an optical circuit capable of properly condensing laser beams. SOLUTION: Convex parts 23a are formed on the incident edge surface of an incident part 23. Cross section of the convex parts 23a is formed into a semi-circular shape in the perpendicular flat plane, including a fast axis direction of laser beam. Thus, the laser beam emitted from a semiconductor laser bar is made to enter the incident part 23 of the optical circuit 20, while largely extending in the fast axis direction and, when entering the incident part 23 of an optical circuit 20, the fast-axis direction is refracted by a large amount. Thereby, almost all of the laser beams emitted from the semiconductor laser bar 10 is made to enter a core 22a of an optical waveguide 22. COPYRIGHT: (C)2007,JPO&INPIT
