Stability of phase locking in coupled semiconductor laser arrays
It is shown that amplitude phase coupling (as described by the linewidth enhancement factor α) leads to unstable phase locking in semiconductor laser arrays with evanescent coup...

Light Modulation and Beam Deflection with Potassium Tantalate-Niobate Crystals
The dielectric and electro-optic properties of KTaxNb1−xO3(KTN) are discussed from the point of view of the material's usefulness in light modulators and beam deflectors. It is ...
Adiabatic theorem and continuous coupled-mode theory for efficient taper transitions in photonic crystals
We prove that an adiabatic theorem generally holds for slow tapers in photonic crystals and other strongly grated waveguides with arbitrary index modulation, exactly as in conve...
Nanowire Plasmon Excitation by Adiabatic Mode Transformation
We show with both experiment and calculation that highly confined surface plasmon polaritons can be efficiently excited on metallic nanowires through the process of mode transfo...
A program for calculating photonic band structures and transmission coefficients of complex structures
We present here a program which will calculate either the photonic band structure or the transmission and reflection coefficients of photons incident on some complex metallic or...
Importance of Spatial and Temporal Dynamics in Species Regional Abundance and Distribution
Several recent models have been proposed to explain the pattern of species distribution within a region. Brown's niche—based model, Levins' stochastic immigration—extinction mod...
Development of an Accurate and Robust Polarizable Molecular Mechanics Force Field from ab Initio Quantum Chemistry
We have produced a polarizable force field for a series of small molecules, representative of functional groups found in organic and biochemical systems. We have used high-level...
Estimates of aerosol radiative forcing from the MACC re-analysis
Abstract. The European Centre for Medium-range Weather Forecast (ECMWF) provides an aerosol re-analysis starting from year 2003 for the Monitoring Atmospheric Composition and Cl...
Optical Rheology of Biological Cells
A step stress deforming suspended cells causes a passive relaxation, due to a transiently cross-linked isotropic actin cortex underlying the cellular membrane. The fluid-to-soli...
Effect of low-power nonlinear refraction on laser-beam propagation in InSb
By use of an expansion in Gaussian functions we solve the problem of the propagation of a laser beam that has been passed through a thin slab of nonlinearly refracting material....
Retrieval of the optical properties of aerosols from aureole and extinction data
Solution of the small-angle approximation of Weinman et al.1 is piled on the solution of the truncation approximation to synthesize the intensity field in the solar aureole. Acc...
