More Information
Summary:There is provided an optical fiber protection structure capable of mitigating deterioration of optical characteristics of an optical fiber under a high-temperature environment and a method of manufacturing an optical element using the same. An optical combiner structure protects bare fiber exposure portions in which bare fibers are exposed from the coverings of optical fibers. The optical combiner structure has a fiber accommodation portion having a fiber accommodation groove that accommodates the bare fiber exposure portions therein, fixation resins filled within the fiber accommodation groove for fixing a portion of the coverings within the fiber accommodation groove, and seal resins for sealing spaces between the bare fibers and the coverings on ends of the bare fiber exposure portions. The seal resins are formed so as to be spaced from an inner surface of the fiber accommodation groove.
