ABSTRACT:
An optical filter module having a multilayered filter inserted in the paths of optical waveguides thereof. In the optical filter module, precise V-shaped grooves are formed on the principle plane of a plane substrate so that optical fibers protrude therefrom. The optical fibers are mounted on the plane substrate. After the multilayered filter is inserted in a filter insertion groove that is formed so as to intersect the V-shaped grooves on the plane substrate, the filter is sandwiched and clamped by two sheets of covers provided on the plane substrate. Provided is a method of precisely mounting the filter that improves the optical axis adjustment between input and output optical fibers and reduces misregistration of the filter to be inserted.
