Optical Vortices Crystals: Spontaneous Generation in Nonlinear Semiconductor Microcavities
Abstract
Broad-area, vertical-cavity surface-emitting lasers were shown to switch their emission mode from the regular single or multilobed light fields to exhibit complex arrays of “dark beams.” Examination of these dark spot arrays revealed that they consist of multiple, closely packed optical vortices: optical fields that have phase singularities and show increased complexity as the injection current level is raised. Contrary to their complex appearance, most of these light distributions are not the result of a multimode (multiple-frequency) operation but exhibit single-frequency characteristics. The dark beam patterns can be described as emanating from a spontaneous process of transverse mode locking of nearly degenerate modes, assisted by the laser nonlinearity. Surprisingly, these patterns show high resemblance to patterns generated in other nonlinear scenarios that are completely different both in scale and in mechanism.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
