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…
Enhanced vibrational optical activity by near-zero index chiral effective media
Ashis Paul, Matteo Venturi, Raju Adhikary +8
The enhancement of the inherently weak optical activity of solvated molecules by superchiral fields, crucial for detecting their chirality, is a research frontier of photonics and…
Spatial beam dynamics in graded-index multimode fibers under Raman amplification:a variational approach
Ashis Paul, Anuj P. Lara, Samudra Roy +1
We investigate the spatial beam dynamics inside a multimode graded-index fiber under Raman amplification by adopting a semi-analytical variational approach. The variational analysi…
Spatial dissipative solitons in graphene-based active random metamaterials
Ashis Paul, Andrea Marini, Samudra Roy
We investigate dissipative nonlinear dynamics in graphene-based active metamaterials composed of randomly dispersed graphene nano-flakes embedded within an externally pumped gain m…
