An optical fiber wavelength filter which has superior optical properties and a manufacturing method for the same are disclosed. The optical fiber wavelength filter is composed of: a pair of glass ferrules which are transparent to ultraviolet rays and which are provided with optical fibers; and a thin dielectric multilayer film filter fixed between the distal ends of the ferrules. To manufacture the optical fiber wavelength filter, the optical fibers are bonded and secured to the pair of glass ferrules which are transparent to ultraviolet rays and the end surfaces thereof are ground. Then, the multilayer film filter and an adhesive agent which is hardened by the ultraviolet rays are disposed between the distal ends of the ferrules with the optical fibers, and the optical axes are aligned using a V-groove aligning jig. Upon completion of the optical axis alignment, ultraviolet rays are irradiated from outside to cure the adhesive agent to instantly fix the filter integrally to the distal ends of the pair of ferrules. <IMAGE> |
