Abstract: PROBLEM TO BE SOLVED: To provide an optical switch in which a liquid having the same refractive index as that of a waveguide for optical communication and a bubble having a refractive index different from that of the waveguide are moved at high speed in a slit by a mechanism based on a gas pump principle. SOLUTION: In the slit 3 in which the liquid 1 and the bubble 2 occupy approximately the same volume, respectively, the surface tension of the lower part of the boundary face of the liquid 1 and the bubble 2 is decreased by heating a heater 401 shown in the figure (a), a state in which the lower valve of a pump is open is realized, the bubble 2 is thermally expanded with a heater 501, the liquid 1 is pushed out toward the lower part of the bubble 2 with the pumping force of the gas, thus the bubble 2 is moved in the opposite direction and the bubble 2 and the liquid 1 counter change the positions at high speed according to the law of inertia even when heaters 402 and 502 are turned off. The slit is used as an optical switch element and an optical matrix switch by locating the slit at the crossing point of crossing optical wave guides.
