Abstract
A light deflector is composed of an electro-optic photonic crystal in which refraction angle of light incident from outside can be controlled by controlling an electric field applied to the electro-optic photonic crystal so as to change the refractive index of the material constituting the photonic crystal and in which the change in the refraction angle in response to the change in the unit refractive index of the material is 103 degrees or more. An optical switch includes the light deflector and a photonic crystal waveguide, the photonic crystal waveguide having a photonic bandgap for light of a predetermined wavelength and also having at least one waveguide which passes the light of the predetermined wavelength.
Claims15
A light deflector comprising an electro-optic photonic crystal in which the refraction angle of light incident from outside can be controlled by controlling an electric field applied to the electro-optic photonic crystal so as to change the refractive index of the material constituting the photonic crystal and in which the change in the refraction angle in response to the change in the unit refractive index of the material is 103 degrees or more.
An optical device comprising:
- a light deflector comprising a photonic crystal having a first dielectric member and configured to change the refractive angle of incident light in response to an electric field applied to the crystal, wherein the electric filed changes the refractive index of the first dielectric member.
