摘要：Precise V-grooves allowing an optical fiber to project are formed in respective
main surfaces of an upper plane substrate and a lower plane substrate. The optical fiberis mounted on one plane substrate, and a multi-layer film filter 2 is inserted into a filterinsertion groove 1 crossing the precise V-groove in the main surface of the other planesubstrate. Then, using the projecting optical fiber and the other precise V-groove as aguide rail, two plane substrates grapple the multi-layer film filter to fix and mount thefilter. In an optical filter module obtained in this manner, a process of adjusting an opticalaxis between input/output optical fibers is eliminated, and displacement of the insertedoptical filter is reduced.
