چکیده

This article presents a study of Poincaré-mode patterns produced by superpositions of high-order Laguerre-Gauss modes in orthogonal polarization eigenstates. We cover the cases of three polarization bases: circular, linear and elliptical. We show that a variety of patterns can be created, many containing polarization singularities and multiple mappings of the Poincaré sphere onto the beam mode.

Orbifold construction of the modes of the Poincaré dodecahedral space

We provide a new construction of the modes of the Poincaré dodecahedral space S3/I∗. The construction uses the Hopf map, Maxwell’s multipole vectors and orbifolds. In particular, the *235-orbifold serves as a parameter space for the modes of S3/I∗, shedding new light on the geometrical significance of the dimension of each space of k-modes, as well as on the modes themselves.

Preparation of Poincaré beams with a same-path polarization/spatial-mode interferometer

We present a same-path polarization interferometer that uses two spatial light modulators to encode the most general type of Poincaré beam. We demonstrate this design by presenting new results on the encoding of symmetric C-point polarization singularities using spatial modes with high-order topological charges. We also present new results on composite C-points. These are cases where there are ...

Space-Variant Polarization Patterns of Non-collinear Poincaré Superpositions

We present analysis and measurements of the polarization patterns produced by non-collinear superpositions of Laguerre-Gauss spatial modes in orthogonal polarization states, which are known as Poincaré modes. Our findings agree with predictions (I. Freund Opt. Lett. 35, 148-150 (2010)), that superpositions containing a C-point lead to a rotation of the polarization ellipse in 3-dimensions. Here...

Comparison of the Effect of Three LED Light Modes and Conventional QTH Curing Light on Shear Bond Strength of Composite to Dentin

  Objective: Shear bond strength is an important property inherent to the durability of tooth-colored restorative materials namely composite resins. It has been years that halogen light sources have been used for polymerization of composite resins. In recent years Light Emitting Diodes (LED) have been introduced for this purpose. With respect to their longer bulb life, needless of a filter and ...

Numerical Calculation of Resonant Frequencies and Modes of a Three-Atom Photonic Molecule and a Photonic Crystal in an External Cavity

In the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. First, governing formulation in transverse electric field mode (TE) is obtained using Maxwell equations. Then, an algorithm based on a finite difference scheme and matrix algebra is presented. The algorithm is then implemented in a comp...
