Abstract

A vertical-cavity surface-emitting laser (VCSEL) is current-annealed to operate in the high order (0,4) Laguerre mode, and this source is used in a superresolution setup to achieve a spot size smaller than the classical diffraction limit. Theory predicts a reduction down to 51% of the classical limit in each dimension (i.e. 4 × reduction in area), and a reduction down to 65% (i.e. 2.5 × reduction in area) is experimentally demonstrated with a signal-to-noise ratio of > 10 dB between the main-lobe and the side-lobe intensities.
