Document Type and Number:
Japanese Patent JP4024570
Kind Code:
B2
Abstract:
The invention relates to structure and arrangement for causing incident light polarization to enter a minute aperture 206 while controlling or preserving the incident light polarization. They are characterized in that one location of the contour of the minute aperture 206 is substantially perpendicular to the direction of polarization of incident light. It can realize near-field optical-generating element, near-field optical recording device, and near-field optical microscope of the minute aperture type capable of improving both the intensity of near-field light and the resolution.
