摘要
Methods and devices for generating multiple, closely spaced, independently controlled near-field light sources are disclosed. By providing an aperture having at least two, orthogonally oriented ridge structures, two or more closely spaced near-field light sources can be generated by controlling the polarization direction of the illuminating radiation. Control of the shape of the aperture, and relative dimensions of the ridge structures allows optimization of the relative intensities of the near-field sources.
