Claims

[Scope of utility model registration request]

a substrate whose refractive index changes depending on temperature as light propagates; a pair of temperature gradient generating means provided on opposing surfaces of the substrate to generate a temperature gradient within the substrate toward the opposing surfaces; An optical deflector comprising a switch that selectively operates this temperature gradient generating means.
