The concave mirror where production manner of optical fiber reflected module and production manner of the optical filter module which uses that, inside the sleeve of the production mannered null cylindrical shape

摘要

PROBLEM TO BE SOLVED: To obtain an inexpensive device by reducing the number of components and facilitating alignment fixing operation.;SOLUTION: The optical fiber reflection module includes a two-core fiber ferrule 11 fitted into a cylindrical sleeve 20 and a concave mirror 21, typically an ellipsoidal mirror, which has two focal points each positioned in two optical fibers 2, 5 in the end face of the two-core fiber ferrule 11 and which is fitted into the sleeve 20. The concave mirror 21 has a base body composed of a molded member with at least one resin or glass concave and has a reflection film 22 stuck to the concave of this base body.;COPYRIGHT: (C)2007,JPO&INPIT
