Abstract
An optical modulator includes a dielectric layer and a metal layer arranged on the dielectric layer. In the optical modulator, a first light of a first frequency and a second light of a second frequency that are incident upon the metal layer exit from the metal layer at different refractive angles due to surface plasmon generation.
Claims18
An optical modulator comprising:
- a dielectric layer;
- and
- a metal layer arranged on the dielectric layer,
- wherein a first light of a first frequency and a second light of a second frequency, which are each incident upon the metal layer, exit from the metal layer at different refractive angles due to surface plasmon generation.

A method of manufacturing an optical modulator, the method comprising:
- forming a dielectric layer;
- and
- forming a metal layer in an area on a surface of the dielectric layer,
- wherein a refractive angle of light exiting from the metal layer depends on at least one from among a thickness and a width of the metal layer.
1 more element
An optical modulator comprising:
- a dielectric layer;
- and
- a metal layer arranged on the dielectric layer and which guides incident light;
- wherein an incident end through which light is incident on the metal layer, and an exit end through which light exits from the metal layer are both perpendicular to a lengthwise direction of the metal layer.
