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…
Optical beam propagation inside a graded-index fiber with saturable nonlinearity
Tiyas Das, Anuj P. Lara, Samudra Roy +1
We study theoretically the spatial evolution of optical beams inside a graded-index fiber exhibiting saturable nonlinearity. Utilizing an approach based on the variational principl…
Bistable quartic soliton in saturable nonlinear media
Tiyas Das, Anuj Pratim Lara, Samudra Roy
This report presents a theoretical demonstration of a novel bistable quartic soliton (BQS) in saturable nonlinear media, specifically within a realistic dispersion-engineered ridge…
A comprehensive study on beam dynamics inside symmetrically chirped waveguide array mimicking the graded index media
Anuj P. Lara, Samudra Roy
In this article, we explore the beam dynamics within symmetrically chirped nonlinear waveguide arrays, focusing on linear and quadratic chirping schemes. We propose a practical str…
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…
