摘要： PROBLEM TO BE SOLVED: To provide an optical switch whose structure is simple, and in which fault hardly occurs, and which is inexpensive by utilizing photonic crystal optical fibers. SOLUTION: An optical switch of this invention is an optical switch in which PCFs (Photonic Crystal Fibers) in each of which a plurality of tube-shaped holes 4 are formed in the clad part 2 around the axial center part 3 becoming a core along the axial center are used. In the optical switch, a coupler part 22 is formed by binding and joining respective vicinity of end parts of a line of the PCF1 (A) becoming an input side and, for example, two lines of PCF1s (B) becoming an output side in such a manner that respective end parts are made to face with each other. When the holes 4 of the PCF1 (A) of the input side and a selected PCF1 (B) of one side of the output side are filled with refractive index matching oil 5 respectively, holes do not exist substantially and PBG (Photinic Band Gap) structure is lost and since the PCF1 (A) and the selected PCF1 (B) lose respectively a function which confines light within the core, light passing through the core 3 is leaked to the clad part 2. As a result, the switching of an optical path from the PCF1 (A) of the input side to the selected PCF1 (B) of one side of the output side is performed. COPYRIGHT: (C)2006,JPO&NCIPI
