Parametric instabilities of microcavity polaritons in a periodic potential
We analyze parametric instabilities of microcavity polartions in the presence of one-dimensional periodic potentials. Instabilities appear in a certain window of pump momentum orientations with respect to the potential so that...
Microfiber-Lithium Niobate on Insulator Hybrid Waveguides for Efficient and Reconfigurable Second-Order Optical Nonlinearity on a Chip
We present an optical microfiber-lithium niobate on insulator (MF-LNOI) hybrid waveguide for efficient second-order nonlinear processes. The structure combines the advantages of low-loss fiber and high-nonlinearity waveguide...
Dispersion of nonlinearity in subwavelength waveguides
Description of pulse propagation in waveguides with subwavelength features and high refractive index contrasts requires an accurate account of the dispersion of nonlinearity due to the considerable mode profile variation with...

Surface-induced nonlinearity enhancement of TM modes in planar subwavelength waveguides
Using an asymptotic expansion of Maxwell equations and boundary conditions, we derive an amplitude equation for nonlinear TM modes in planar metal and dielectric waveguides. Our approach reveals that the physics of the...
Surface-induced nonlinearity enhancement in subwavelength rod waveguides
We develop a perturbative theory to describe optical propagation in subwavelength rod waveguides. In this approach, we account for loss and nonlinearity in the boundary conditions. A comparison to the traditional perturbative...

Evaluation of template-based modeling in CASP13.
Performance in the template-based modeling (TBM) category of CASP13 is assessed here, using a variety of metrics. Performance of the predictor groups that participated is ranked using the primary ranking score that was developed...

Phosphides are interesting candidates for hole transport materials and p-type transparent conducting applications, capable of achieving greater valence band dispersion than their oxide counterparts due to the higher lying energy...
Solitons in hollow core photonic crystal fiber
