Abstract
Optical elementaccording to the present invention comprises light guide body, surface plasmon excitation meansthat is provided on the interface with light guide bodyand that allows surface plasmon to be excited by a specific polarization component of light whose polarization direction is orthogonal to the first direction y in the surface of light guide body, from among light entering from light guide body, and a light generation means that includes metal layerand cover layer, and that generates light having the same polarization component as the specific polarization component of light, from surface plasmon produced in the interface between metal layerand cover layerin response to surface plasmon excited by the specific polarization component in surface plasmon excitation means. Surface plasmon excitation meansincludes a plurality of protrusions, each of which extends in the first direction y and is periodically arrayed along the second direction x orthogonal to the first direction y.
