We investigate the effect of nonlinearity in novel parity-time (PT) symmetric potentials. We show that new types of nonlinear self-trapped modes can exist in optical PT synthetic lattices.
An exact analytical solution for the evolution of stimulated Raman crosstalk in a singlemode WDM fiber system is presented utilizing the triangular approximation to the Raman gain spectrum. This… (More)
We show that three approaches previously developed to describe partially incoherent wave propagation in inertial nonlinear media are in fact equivalent. This equivalence is formally established… (More)
In all of the diverse areas of science where waves play an important role, one of the most fundamental solutions of the corresponding wave equation is a stationary wave with constant intensity. The… (More)
It is shown that discrete solitons can be navigated in two-dimensional networks of nonlinear waveguide arrays. This can be accomplished via vector interactions between two classes of discrete… (More)
By exploiting the reflection symmetry of the underlying evolution equations, we theoretically demonstrate that stimulated Raman scattering crosstalk in continuous-wave wavelength-division-multiplexed… (More)
We present a new strategy for regulating light emission dynamics in high power laser arrays. Our approach is based on engineering the properties of non-Hermitian supersymmetric optical arrays and… (More)
We present numerical analysis of white-light solitons in noninstantaneous nonlinear media, and lay down general requirements for soliton formation.
We report the first experimental observation of vector discrete solitons. We find that at appropriate power levels two orthogonally polarized beams collapse into a highly confined vector discrete… (More)
We predict and present the first observation of conical diffraction arising from k-space singularities in the band-structure of a periodic potential. The experiments are carried out in honeycomb… (More)
