Static and breathing dynamics of optical bullets in nonlinear GRIN fibers
Sonali Maity, Tiyas Das, Anuj P. Lara +2
We explore the properties of spatiotemporal solitons within nonlinear graded-index (GRIN) optical fibers, specifically addressing their formation, stability, and breathing dynamics…

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…
