Vorticity cutoff in nonlinear photonic crystals [PDF]
Physical Review Letters, 2004 Using group theory arguments, we demonstrate that, unlike in homogeneous media, no symmetric vortices of arbitrary order can be generated in two-dimensional (2D) nonlinear systems possessing a discrete-point symmetry.

Nonlinear Photonic Crystals: IV. Nonlinear Schrodinger Equation Regime [PDF]
Waves in Random and Complex Media, 2005 We study here the nonlinear Schrodinger Equation (NLS) as the first term in a sequence of approximations for an electromagnetic (EM) wave propagating according to the nonlinear Maxwell equations (NLM).

Solitons in quadratic nonlinear photonic crystals [PDF]
Physical Review E, 2000 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 ...

Nonlinear interference in crystal superlattices [PDF]
Light: Science & Applications, 2020 AbstractNonlinear interferometers with correlated photons hold promise to advance optical characterization and metrology techniques by improving their performance and affordability. These interferometers offer subshot noise phase sensitivity and enable measurements in detection-challenging regions using inexpensive and efficient components.
