Effects of ultrafast free-carrier dynamics on frequency comb generation in graphene-based microresonators
Ambaresh Sahoo
Manipulation of the dynamics of cavity solitons, precise control of frequency comb spectra and nonlinear response of microresonators through exploitation of the ultrafast optical p…
Stability and variational analysis of cavity solitons under various perturbations
Ambaresh Sahoo, Samudra Roy
We theoretically investigate the dynamics and stability of a temporal cavity soliton (CS) excited inside a silicon-based microresonator that exhibits free-carrier generation as a r…
Heat-induced soliton self-frequency redshift in the ultrafast nonlinear dynamics of active plasmonic waveguides
Ambaresh Sahoo, Andrea Marini, Samudra Roy
We investigate the ultrafast nonlinear dynamics of light emitted in an active plasmonic waveguide composed of a thin film of gold sandwiched by two silicon layers immersed in exter…
Dissipative solitons in self-defocussing nonlinear media: The curious case of zero-nonlinearity point
Ambaresh Sahoo, Samudra Roy
We theoretically model a dissipative system which exhibits self-defocussing nonlinearity and numerically study the dynamics of optical dissipative solitons (DSs) whose evolution is…
Perturbed Dissipative Solitons: A Variational Approach
Ambaresh Sahoo, Samudra Roy, Govind P. Agrawal
We adopt a variational technique to study the dynamics of perturbed dissipative solitons, whose evolution is governed by a Ginzburg--Landau equation (GLE). As a specific example of…
