FIXING STRUCTURE FOR OPTICAL FIBER, SEMICONDUCTOR LASER MODULE, AND FIXING METHOD FOR OPTICAL FIBER

摘要

This fixing structure for an optical fiber comprises a groove (15) that is provided to a fiber-fixing base (9) along the axial direction of an optical fiber (13) to be fixed. The groove (15) opens upward. The optical fiber (13) is arranged within the groove (15) along the groove (15). The optical fiber (13) is fixed to the inner surface of the groove (15) using an adhesive (11). On this occasion, the inner-side surfaces of the groove (15) that face each other serve as fixing surfaces (17) for the optical fiber (13). In other words, the optical fiber (13) is fixed to the fixing surfaces (17) that are the inner-side surfaces of the groove (15) and that face each other using the adhesive (11). A space (19) in which the fiber fixing base (9) and the adhesive are not bonded is formed in the vertical direction of the optical fiber (13). In other words, a space (19) is provided in a vertical direction that is substantially perpendicular to the fixing direction in which the optical fiber (13) is fixed.
