Embodiment Construction

[0021] In the present invention, at least the component boxes located at both ends of the module have collimators. In addition, the present invention, for example, improves the component box to allow fine adjustment of the position of the collimator. A collimator insertion portion is provided at the center of the component box, and an adjustment mechanism is provided in a hole located above it and a hole extending in a lateral direction. Therefore, when the module is actually set up, after installing multiple component boxes on the substrate, the position of the collimator can be adjusted so that the optical coupling of each component box and the optical coupling of the fiber collimator can reach the best state. The adjustment mechanism is, for example, a screw that can be manually operated to move, or an actuator (Actuator) that can move a position by an electric command. The position of the collimator can be optimized by this adjustment mechanism, so even if a fiber-type or...

Abstract

The invention provides a box-type optical function module, which can realize good optical coupling, and has a fiber-type module or a waveguide-type module. The invention relates to a box-type optical function module (10), which has: first and second optical fiber collimators (2, 3); an optical function unit (5), which has an optical fiber Type module or waveguide type module; Base part (7). In addition, the optical functional unit (5) has: a third collimator (13); a first position adjustment mechanism (17), which is used to adjust the position of the third collimator (13) in the optical functional unit 5.

Description

technical field [0001] The invention relates to a fiber optic functional element box module. Background technique [0002] An optical functional element box module is disclosed in Japanese Patent Publication No. 3933967 (Patent Document 1). The box-type optical functional module disclosed in this document targets bulk type optical functional components. [0003] [Patent Document 1] Japanese Invention Patent Publication No. 3933967 [0004] In addition, there is a need in the prior art for modules using optical elements other than bulk optical elements. However, when an optical fiber type module or a waveguide type module is to be installed in the component box of the module disclosed in Japanese Invention Patent Publication No. 3933967 (patent document) 1, there will be a gap between the optical fiber collimators positioned at both ends of the module. The problem of not getting good optical coupling between them. [0005] In the existing optical functional element box mo...
