| 英文摘要 | PURPOSE:To reduce reflection returning light from a fiber end to laser and simplify their coupling with high efficiency by a method wherein when laser light from a semiconductor laser is incident on an optical fiber, angle is secured between an optical axis of the laser light and a direction of a groove for guiding the optical fiber. CONSTITUTION:A semiconductor laser 11 is mounted on a submount 18, and when light 19 from this is incident to an optical fiber clad 13 having a core 14, the optical axis 15 of an optical fiber 20 is tilted with respect to the optical axis 12 of the incident light by specific angle. That is, a V-shaped groove 17 for guiding the optical fiber having a slope approximately 10 deg. (theta1) with respect to the submount 18 is provided in advance, and the optical fiber 20 which has been obliquely ground along the groove 17 by 8 deg. (theta2) which is optimum ground angle is installed to be fixed by using resin or the like. Thus angle of 10 deg. is generated between the optical axis 15 of the fiber 20 and the optical axis 12 of the laser light 11 so that outgoing light L1 is refracted when it is incident to the fiber 20 and propagation light L2 is propagated along the optical axis 15. |
