Orbital Angular Momentum preserving guided mode in helically twisted hollow core photonic crystal fiber at Dirac point
Rik Chattopadhyay, Shyamal K. Bhadra
We report trapping and propagation of photonic Dirac mode in a helically twisted hollow core photonic crystal fiber (HC-PCF) where the trapped light in the hollow (air) defect can…
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…
Experimental and theoretical study of red-shifted solitonic resonant radiation in photonic crystal fibers and generation of radiation seeded Raman solitons
Surajit Bose, Samudra Roy, Rik Chattopadhyay +2
The red shifted solitonic resonant radiation is a fascinating phase matching phenomenon that occurs when an optical pulse, launched in the normal dispersion regime of photonic crys…
Design and fabrication of an intrinsically gain flattened Erbium doped fiber amplifier
B. Nagaraju, M. C. Paul, M. Pal +6
We report design and subsequent fabrication of an intrinsically gain flattened Erbium doped fiber amplifier (EDFA) based on a highly asymmetrical and concentric dual-core fiber, in…
