Abstract:
1. A probe for generating near-field light from an aperture by irradiating a tip having the aperture with polarized light, said probe comprising: said tip, wherein said tip comprises a cone-shaped lightproof member, wherein the top of said cone-shaped lightproof member is in the shape of a rectangular-shaped plane, wherein the aperture is provided in the rectangular-shaped plane of the top, wherein said cone-shaped lightproof member is configured so that irradiated polarized light is reflected at an inner surface of said cone-shaped lightproof member, wherein the width of the aperture is smaller than the wavelength of the irradiated polarized light, wherein the interior width of the rectangular-shaped plane of the top is larger than the width of the aperture, wherein the interior width of the rectangular-shaped plane of the top is in the range from 400 nm to 1400 nm, and wherein the irradiated polarized light is parallel to a long side or a short side of the rectangular-shaped plane of the top.
