Abstract:
An optical fiber wavelength filter comprising:a pair of ferrules aligned with each other on a V-grooved support member, each having a distal end surface slanted at an angle predetermined with respect to the optical axis thereof, and each of which is composed of a material transparent to a light ray containing a particular wavelength component;a pair of optical fibers supported by said ferrules and having end surfaces, wherein said distal end surfaces of said optical fibers are ground together with the end surfaces of said ferrules and polished at said predetermined angle;a thin dielectric multilayer film filter disposed between the polished distal end surfaces of said ferrules; andan adhesive agent put on the surfaces of said pair of ferrules and said thin dielectric multilayer film filter, which is cured by irradiating said pair of ferrules and said dielectric multilayer film filter at the same time with a light ray containing said particular wavelength component, while both said pair of ferrules and said dielectric multilayer film filter are kept mounted on said V-grooved support member, and is solidified thereat.
