Abstract

An analysis of the enhancement of light transmission through a sub-wavelength aperture by oil- or solid-immersion is presented in this letter. An output power enhancement phenomenon related to the oil-immersion or solid-immersion mechanism is realized experimentally and reported for a very-small-aperture laser, which is in agreement with simulation analysis. This phenomenon could be useful for future optical data storage, microscopy and lithography. A graph is presented.
