Design of an efficient mid-wave IR fiber optic light source
A. Barh, S. Ghosh, R. K. Varshney +1
Design of a mid-wave IR broadband (3.1 - 3.8 μm) fiber-based light source exploiting FWM in a meter long suitably designed chalcogenide microstructured fiber is reported. An achiev…
Generation of Low Divergent High Power Supercontinuum Through a Large Mode Area Photonic Bandgap Fiber
S. Ghosh, T. Naresh, R. K. Varshney +1
We report generation of broadband low divergent supercontinuum over the entire wavelength window of 1.5 to 3.5 μm from a 2.25 meter long effective single moded photonic bandgap fib…
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…
Transverse localization of light in 1D disordered waveguide lattices with backbone photonic bandgap
Somnath Ghosh, B. P. Pal, R. K. Varshney +1
The role of a prominent photonic bandgap (PBG) on the phenomenon of transverse localization of light in a semi-infinite lossless waveguide lattice consisting of evanescently couple…
