Spatial dissipative solitons in graphene-based active random metamaterials
Ashis Paul, Andrea Marini, Samudra Roy
We investigate dissipative nonlinear dynamics in graphene-based active metamaterials composed of randomly dispersed graphene nano-flakes embedded within an externally pumped gain m…
Intra-cavity field dynamics near avoided mode crossing in concentric silicon nitride ring resonator
Maitrayee Saha, Samudra Roy, Shailendra K. Varshney
Understanding the intra-cavity field dynamics in passive microresonator systems has already been intriguing. It becomes fascinating when the system is complex, such as a concentric…
Dynamic diffractive resonant radiation in a linearly chirped nonlinear waveguide array
Anuj P. Lara, Samudra Roy
We theoretically and numerically investigate the evolution of discrete soliton in a 1D linearly chirped nonlinear waveguide array (WA). The discrete soliton is self-accelerated ins…
Dynamics and selective temporal focusing of a time truncated Airy pulse in varying dispersive medium
Aritra Banerjee, Samudra Roy
We theoretically investigate the dynamics of a time truncated Airy pulse under longitudinally varying dispersion. The realistic waveguide geometry is proposed that offers linear or…
Trajectory manipulation of an Airy pulse near zero dispersion wavelength under free carrier generated linear potential
Aritra Banerjee, Samudra Roy
We investigate the dynamics of an Airy pulse that experiences free carrier generated optical linear potential in the vicinity of zero group velocity dispersion (GVD) wavelength ins…
Variational approach to study soliton dynamics in a passive fiber loop resonator with coherently driven phase-modulated external field
Maitrayee Saha, Samudra Roy, Shailendra K. Varshney
We report a detailed semi-analytical treatment to investigate the dynamics of a single cavity soliton (CS) and two co-propagating CSs separately in a Kerr mediated passive optical…
