IR Image Upconversion Under Dual-Wavelength Laser Illumination
IEEE Photonics Journal, 2016 We investigate the use of dual-wavelength laser illumination in a nonlinear infrared-to-visible image upconversion system. We show how a two-wavelength laser illumination can combine the enhanced upconversion field-of-view (FOV) characteristic of ...

Superprism phenomena in planar photonic crystals
, 2010 We utilize the anomalous dispersion of planar photonic crystals near the dielectric band edge to control the wavelength-dependent propagation of light. We typically observe an angular swing of up to 10degrees as the input wavelength is changed from 1290 ...

Solitons in quadratic nonlinear photonic crystals [PDF]
Physical Review E, 2001 We study solitons in one-dimensional quadratic nonlinear photonic crystals with modulation of both the linear and nonlinear susceptibilities. We derive averaged equations that include induced cubic nonlinearities and numerically find previously unknown soliton families.

Mechanism of wave breaking from a vacuum point in the defocusing nonlinear Schrödinger equation
, 2014 We study the wave breaking mechanism for the weakly dispersive defocusing nonlinear Schrödinger equation with a constant phase dark initial datum that contains a vacuum point at the origin.

Superluminal k-gap solitons in nonlinear photonic time-crystals
, 2022 We propose superluminal solitons residing in the momentum gap (k-gap) of nonlinear photonic time-crystals. These gap solitons are structured as plane-waves in space while being periodically self-reconstructing wavepackets in time.
