<P>PROBLEM TO BE SOLVED: To provide the optical filter array for an optical fiber capable of coping with the wavelength variation of the transmission side. <P>SOLUTION: In the optical filter array for an optical fiber, a transparent substrate and a multilayer interference film provided on the transparent substrate are arranged so that a plurality of input light pass through the multilayer interference film and the transparent substrate. The optical filter array comprises a plurality of input ports and output ports connected to a plurality of optical fibers. The thickness of the interference film to input light from a first input port differs from the thickness of the interference film to input light from an n-th input port. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
