OPTICAL MATERIAL, OPTICAL ELEMENT, AND METHOD FOR MANUFACTURING SAME

摘要

An optical material which has a relative permeability different from 1 to light having a wavelength in, for example, the infrared region or shorter than the infrared region and which is stable in structure, and a liquid and a solid (optical element) using the optical material. The optical material is a powder used as a component of a liquid or solid to which an illuminating light is irradiated, and includes a large number of resonating elements which constitute the powder and each of which is formed of a conductor having a width approximately same as or smaller than a wavelength of the illumination light, and a protective film which is formed of a disc-shaped insulator, wherein an entire surface of each of the split-rind resonators is covered by the protective film.

主权项

1. A method for producing an optical material composed of a plurality of minute resonators each of which is formed of a conductor, and is covered by a protective film formed of an insulator or a semi-conductor, the method comprising:
forming a sacrifice layer on a substrate; forming a first protective layer formed of the insulator or the semi-conductor on the sacrifice layer; forming a conductive layer formed of the conductor on the first protective layer; patterning the minute resonators in the conductive layer; forming a second protective layer formed of the insulator or the semi-conductor so as to cover the patterned minute resonators; and removing the sacrifice layer.
