Linear and Nonlinear Characterization of broadband integrated Si-rich silicon nitride racetrack ring resonator for on-chip applications
Partha Mondal, Venkatachalam P, Radhakant Singh +3
We demonstrate the linear and nonlinear characterization of plasma-enhanced chemical vapor deposited silicon-rich silicon nitride (SRSN) racetrack ring resonator for on-chip applic…
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…
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…
Nanolithography using counter-propagating light-sheets
Kavya Mohan, Partha Pratim Mondal
We propose a laser interference nano-lithography technique for fabrication of nano-structures. This is inspired by a 2pi-illumination system that consists of two cylindrical lens a…
