摘要： Glass can have a high thermal expansion coefficient when it is made up of SiO 2 , B 2 O 3 , Na 2 O, K 2 O, MgO and Al 2 O 3 ; contains a partial crystal; and has a mean thermal expansion coefficient of 125×10 -7 K -1 in a temperature range of 50°C to 150°C. Using this glass as a substrate for a multilayer film filter can fully reduce temperature fluctuations in the filter properties.

摘要： 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.
