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…
Temporal wave trapping from dynamical pump pulses
T. Torres, R. Terrier, J. Fatome +3
Temporal reflection in nonlinear optical fibers provides a powerful framework for manipulatinglight. In this work, we theoretically and experimentally demonstrate a novel mechanism…
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…
Implications of a zero-nonlinearity wavelength in optical fibers doped with silver nanoparticles
S. Bose, S. Roy, R. Chattopadhyay +2
Photonic crystal fibers doped with silver nanoparticles exhibit the Kerr nonlinearity that can be positive or negative depending on wavelength and vanishes at a specific wavelength…
Specialty Fibers for Terahertz Generation and Transmission: A Review
Ajanta Barh, B. P. Pal, G. P. Agrawal +2
Terahertz (THz) frequency range, lying between the optical and microwave range covers a significant portion of the electro-magnetic spectrum. Though its initial usage started in th…
Design of an efficient Mid-IR light source using As2S3 based highly nonlinear microstructured optical fibers
A. Barh, S. Ghosh, G. P. Agrawal +3
We report on the design of a highly-nonlinear specialty fiber as a mid-infrared light source at 4.3 μm. A meter length of the designed solid-core chalcogenide based index-guided mi…
Transverse localization of light and its dependence on the phase-front curvature of the input beam in a disordered optical waveguide lattice
S Ghosh, B P Pal, R K Varshney +1
We investigate the influence of the phase-front curvature of an input light beam on the transverse localization of light by choosing an evanescently coupled disordered one-dimensio…
