PHYSICAL REVIEW A
We investigate second-harmonic generation in III-V semiconductor wire waveguides aligned with a crystallographic axis. In this direction, because of the single nonzero tensor element coming from the zinc-blende symmetry of III-V semiconductors, only

Growth of Organic Crystalline Thin Films with Strong Second-Order Nonlinearity for Integrated Optics

We demonstrate the growth of highly nonlinear crystalline thin films of N-benzyl-2-methyl-4-nitroaniline (BNA) with a controllable crystal orientation. These films are obtained by crystallizing the material in a temperature gradient. Through second-h

Improvement of solar cell performance through the parallel homo-tandem architecture is studied. The cell geometry is optically designed to maximize absorption of the AM1.5 spectrum. We consider both ITO electrode and a recently devised ITO-free alter

In this work, we study the nonlinear propagation of light in liquid crystals (LCs) and the optical gain provided by LCs when they are polymer- or dye-doped.We will focus on nematic LCs, which are characterized by a mean orientation (also called direc

Liquid crystals
A uniform lying helix (ULH) alignment of cholesteric liquid crystals (LCs) is obtained using a solvent evaporation technique. The solvent evaporation method allows for the spontaneous formation of a virtually defect-free alignment, even in the absenc
