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…
Competition Between Intermodal Modulation Instability and Kerr Beam Self-cleaning in Graded-index Multimode Fiber
Partha Mondal, Shailendra K. Varshney
We report the suppression of intermodal modulation instability peaks as a consequence of Kerr induced self beam-cleaning in a 90m long graded-index multimode optical fiber under va…
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…
Modal Group Velocity Mismatch Induced Intermodal Modulation Instability in Step-index Fiber
Partha Mondal, Shailendra K. Varshney
We present detailed experimental study on noise-seeded intermodal modulation instability (IM-MI) in normal dispersion region of a conventional step-index fiber. The sharp refractiv…
Phase Synchronization of Stimulated Raman Process in Optical Fiber For Long Pulse Regime
Partha Mondal, Shailendra K. Varshney
We investigate the evolution of coherence property of noise-seeded Stokes wave in short (< 1 ps) and long pulse (> 1 ps) regimes. Nonlinear equations expressing the evolution of pu…
Generalized Mathematical Formalism Governing Free-carrier Driven Kerr Frequency Comb in Optical Micro-cavities
Raktim Haldar, Arkadev Roy, Partha Mondal +2
Continuous-wave pumped optical microresonators have been vastly exploited to generate frequency comb (FC) utilizing the Kerr nonlinearity. Most of the nonlinear materials used to b…
