Abstract
We investigate optical near-field distributions of theunconventional C-apertures and the conventional square apertures inpreliminary experiment with an aperture scanning near-field opticalmicroscope. These nano-apertures are fabricated in Au film on a glasssubstrate with focused ion beam technology. The experimental resultsindicate the uptrend of output light intensity that a C-aperture enablesthe intensity maximum to increase at least 10 times more than a square aperturewith same unit length. The measured near-field light spot sizes ofC-aperture and square aperture with 200-nm unit length are 439 nm× 500 nm and 245 nm × 216 nm, respectively.
