This optical vortex is studied in the framework of a Maxwell-Bloch model. Clarification is given of the nature of the optical vortex on symmetry grounds. A quantitative analysis is proposed which relies on a Maxwell-Bloch model which was first formulated to describe the phenomenon of spontaneous transverse spatial pattern formation in lasers.

Oct. 1988; 58(10): 1955-65 RT: Journal-Paper AB: An analysis is made of the spatial distribution of the zeros of the amplitude of the complex visibility function and the related branching regions of the low-frequency interference fringes in the field of a superposition of two identical fields displaced relative to each other. The method of stationary phase is used to investigate the nature of the spatial distribution of the surfaces of zero visibility in the volume of the superposition speckle field. It is shown that the phase dislocation and branching of the interference fringes in the characteristic transverse and longitudinal sections through the superposition field are manifested differently depending on the shape of the aperture bounding the entrance pupil of the viewing system. The experimental results exhibit good agreement with the theoretical conclusions.

On a map of contours of equal phase these wave dislocations (interference nulls) are accompanied by saddles. When an external parameter is changed dislocations can be created in pairs or a pair can meet and destroy one another. For the simplest single-frequency wave equation it is a topological necessity that two saddles should participate in this event; moreover, they have to lie, in the final stage before annihilation, on the circle whose diameter is the line joining the dislocations. An example of an annihilation event occurs in the South Atlantic, and a close pair of amphidromic points may explain anomalous tidal observations from the Antarctic Peninsula. The tidal current, as distinct from the tidal rise and fall, provides an example of a two or three-dimensional vector field, and it is pointed out that the singularities in this field are precisely the same as those to be found in the polarization field of an electromagnetic wave.

It consists of three intersecting beams of plane-wave pulses. Because the results depend essentially only on the relative time delays of the three pulses at any given point, the computations have to be done only once, and they are then applicable, by a linear mapping, to any angular arrangement of the three beams. The model produces dislocations showing the most general behaviour: they are curved, with varying edge-screw character, and they glide and climb. The predictions of the theory of Wright and Nye, valid for small bandwidth but not rigorously justified, are shown to be correct for this model. As the bandwidth increases new dislocation behaviour becomes evident: for example, the dislocation trajectories change their connectivity at or close to saddle points for amplitude in the corresponding continuouswave pattern. At lower bandwidths Lorentzian-shaped pulses give dislocations that travel on looped trajectories beginning and ending on the nulls of the corresponding continuous-wave pattern, while at higher bandwidths the trajectories lie in close pairs, with one member having small arrival times for the dislocations and the other having large arrival times.

SO: Journal-of-Physics-A-Mathematical-and-General. 21 Feb. 1986; 19(3): 375-83 RT: Journal-Paper AB: Pulsed wavefields contain moving lines, called wave dislocations, where the amplitude is zero. As the lines move they sweep out surfaces called dislocation trajectories. The authors describe an experiment with ultrasound designed to test the theoretical prediction of Wright and Nye (1982) that, for small bandwidth, the trajectories are close to parts of frequency minimum surfaces. That is, surfaces on which the corresponding continuous-wave amplitude pattern has a minimum with respect to changes in frequency. `Close' here means to second order in the bandwidth, and the prediction is indeed confirmed to this accuracy.
