Two-color pulse compounds in waveguides with a zero-nonlinearity point
O. Melchert, S. Bose, S. Willms +3
We study incoherently coupled two-frequency pulse compounds in waveguides with single zero-dispersion and zero-nonlinearity points. In such waveguides, supported by a negative nonl…
Cherenkov radiation and scattering of external dispersive waves by two-color solitons
Ivan Oreshnikov, Oliver Melchert, Stephanie Willms +5
For waveguides with two separate regions of anomalous dispersion, it is possible to create a quasi-stable two-color solitary wave. In this paper we consider how those waves interac…
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…
