Abstract
The optical switchcomprises a first waveguide, a second waveguide, and an exchanger. The first waveguidecomprises a first end Eand a second end E. The second waveguidecomprises a third end Eand a fourth end E, respectively located on the first end Eside and the second end Eside as viewed from the center of the first waveguide. The exchangercomprises: a first waveguide sectionconfiguring a directional coupler together with the first waveguideand including a phase changing material; and a second waveguide sectionconfiguring a directional coupler together with the second waveguideand including a phase change material. The exchangerinputs electromagnetic waves, input from the first end Eand output from the first waveguide section, to the third end Eside of the second waveguide section. The exchangerinputs electromagnetic waves, input from the third end Eand output from the second waveguide section, to the second end Eside of the first waveguide section
