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…
Mid-IR fiber optic light source around 6 micron through parametric wavelength translation
A Barh, S Ghosh, R K Varshney +4
We report numerically designed highly nonlinear all glass chalcogenide microstructured optical fiber for efficient generation of light around 6 micron through degenerate four wave…
A Tapered Chalcogenide Microstructured Optical Fiber for Mid-IR Parabolic Pulse Generation: Design and Performance Study
Ajanta Barh, S. Ghosh, Ravi K. Varshney +1
This paper presents a theoretical design of chalcogenide glass based tapered microstructured optical fiber (MOF) to generate high power parabolic pulses (PPs) at the mid-IR wavelen…
Ultra-large Mode Area Microstructured Core Chalcogenide Fiber Design for Mid-IR Beam Delivery
Ajanta Barh, Somnath Ghosh, R. K. Varshney +1
An all solid large modearea (LMA) chalcogenide based microstructured core optical fiber (MCOF) is designed and proposed for high power handling in the mid IR spectral regime, cover…
