A Riccati equation approach to construct new dispersive solitons to the Kaup-Newell equation [PDF]
The present paper examines analytically the Kaup-Newell equation, an important class of nonlinear Schrodinger equations with lots of applications in optical fibers. The Riccati equation approach is employed for the present study. The method is one of the

Rotationally induced vortices in optical cavity modes [PDF]
We show that vortices appear in the modes of an astigmatic optical cavity when it is put into rotation about its optical axis. We study the properties of these vortices and discuss numerical results for a specific realization of such a set-up. Our method

Rotating vortex imaging implemented by a quantized spiral phase modulation [PDF]
We demonstrate both theoretically and experimentally that a spiral mask with a finite number of discrete phase levels allows a defocusing induced rotation of the point spread function in the vortex imaging.

Hybridization of singular plasmons via transformation optics [PDF]
Significance Surface plasmons, which are optical resonances supported by metallic nanostructures, are extremely useful for manipulating light on the nanoscale. However, designing novel plasmonic devices becomes quite challenging when the desired spectral response pattern is highly complex.

Vanishing tilt-to-length coupling for a singular case in two-beam laser interferometers with Gaussian beams [PDF]
The omnipresent tilt-to-length coupling in two-beam laser interferometers, frequently a nuisance in precision measurements, vanishes for the singular case of two beams with identical parameters and complete detection of both beams without clipping.

Compound Vector Light Generator Based on a Metasurface
In view of wide applications of vector light with a non-uniform polarization state, a compound vector light generator is proposed to generate compound vector light. One compound vector light contains two or more non-uniform polarization modes and several

Identification of nonlinearity in conductivity equation via Dirichlet-to-Neumann map
We prove that the linear term and quadratic nonlinear term entering a nonlinear elliptic equation of divergence type can be uniquely identified by the Dirichlet to Neuman map.

Creating and Controlling Polarization Singularities in Plasmonic Fields
Nanoscale light fields near nanoplasmonic objects can be highly structured and can contain highly-subwavelength features. Here, we present the results of our search for the simplest plasmonic system that contains, and can be used to control, the smallest
