Robust bistable vortex light bullets in graded-index multimode fibers

Ashis Paul, Anuj P. Lara, Govind P. Agrawal +1

We explore theoretically the formation and evolution of spatiotemporal vortex bullets, pulses confined in both space and time while carrying orbital angular momentum, inside a grad…

Dynamic diffractive resonant radiation in a linearly chirped nonlinear waveguide array

Anuj P. Lara, Samudra Roy

We theoretically and numerically investigate the evolution of discrete soliton in a 1D linearly chirped nonlinear waveguide array (WA). The discrete soliton is self-accelerated ins…
