Abstract

Optical near-field in subwavelength air-dielectric structure is studied by a collection-mode nearfield optical microscopy. Concentrated optical near-field and large polarization anisotropy at the dielectric regions are measured. From the simulation of finite-difference time-domain method, we conclude the edge diffraction dominating the optical near-field distribution.
