概要

• 論文の詳細を見る

• 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.
