Towards self-similar propagation in a dispersion tailored and highly nonlinear segmented bandgap fiber at 2.8 micron
Piyali Biswas, Somnath Ghosh, Abhijit Biswas +1
We numerically demonstrate self-similar propagation of parabolic optical pulses through a highly nonlinear and passive specialty photonic bandgap fiber at 2.8 micron. In this conte…
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…
Confinement of Light in Disordered Photonic Lattices: A New Platform for Waveguidance
Somnath Ghosh, Bishnu P. Pal
A right amount of disorder in the form of refractive index variation has been introduced to achieve transverse localization of light 1D semi-infinite photonic lattices. Presence of…
Design of an all-fiber broadband mid-IR source through wavelength translation
A. Barh, S. Ghosh, R. K. Varshney +1
We report design of an efficient ~ 50 cm long all-fiber compact microstructured optical fiber-based 3-4.25 um mid-IR light source with power conversion efficiency > 28% by exploiti…
Effect of a weak longitudinal modulation in refractive index on transverse localization of light in 1D disordered waveguide lattices
Somnath Ghosh, R. K. Varsheny, Bishnu P. Pal
We report the enhancement of the effect of transverse localization of light (TL) in presence of a weak longitudinal modulation of refractive index in disordered waveguide lattices.…
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…
