Abstract
The present application discloses an optical switch, including a first optical waveguide, a second optical waveguide, and a first heater, where a place at which a distance between the first optical waveguide and the second optical waveguide is the smallest is a junction; the first heater is adjacent to the third optical sub-waveguide; and there is a first dielectric material between the first heater and the third optical sub-waveguide, and there is a second dielectric material between the third optical sub-waveguide and the fourth optical sub-waveguide, where a thermal conductivity of the first dielectric material is greater than a thermal conductivity of the second dielectric material. The optical switch has advantages such as high heating efficiency, a small quantity of heaters, and simple control.
