Abstract

A first light reflection surface (51) and a second light reflection surface (52) are formed on a lower half of a mirror block (50) in a state that these light reflection surfaces (51), (52) make 90 degrees therebetween. A first light reflection surface (51) and a second light reflection surface (52) are also formed on an upper half of the mirror block (50) in a state that these light reflection surfaces (51), (52) make 90 degrees therebetween. A third light reflection surface (53) and a fourth light reflection surface (54) are formed between the first light reflection surface (51) and the second light reflection surface (52) such that these light reflection surfaces (53), (54) make 90 degrees therebetween. According to this optical switch, by changing a region which reflects the light between the upper half and the lower half of the mirror block (50), the coupling relationship between an input optical fiber and an output optical fiber can be changed over.

Dependent claims

An optical switch including at least three input and output optical paths in total and performing the changeover of the optical paths by changing the combination of the input optical path and the output optical path which transmit light to each other, wherein

a first region in which a front surface of a mirror member which is movable relative to the input optical path and the output optical path is allowed to face the input optical path and the output optical path thus forming a pair of light reflection surfaces which cross each other with a given angle, and a second region in which a plural pairs of light reflection surfaces are formed in a state that the neighboring light reflection surfaces cross each other with given angles, are arranged in front of the mirror member and along the moving direction of the mirror member.

Dependencies are inferred from the claim text.
