Engineering Multi-wavelength Emission in All-Fiber Laser Mode-Locked Through Nonlinear Polarization Rotation
Subrata Manna, Amala Jose, K. Nithyanandan
The increasing demand for multi-wavelength optical sources to support dense wavelength-division multiplexing (DWDM) channels has driven the development of compact and reconfigurabl…
Propagation of Gaussian beam in strongly nonlocal nonlinear media with inhomogeneous diffraction
K L Mamatha, S Stalin, K Nithyanandan
Solitons in a strongly nonlocal nonlinear medium have attracted considerable attention in recent years due to their unique and distinctive characteristics from those observed in th…
Multistability and Switching in Oppositely Directed Saturable Coupler
K. Nithyanandan, A. K. Shafeeque Ali, M. P. M. Nishad +3
We report a novel optical multistability in two core oppositely directed saturable coupler (ODSC) with negative index material (NIM) channel. The dynamics are studied using the Lan…
Real-time observation of dissipative optical soliton molecular motions
Katarzyna Krupa, K. Nithyanandan, Ugo Andral +2
Real-time access to the internal ultrafast dynamics of complex dissipative optical systems opens new explorations of pulse-pulse interactions and dynamic patterns. We present the f…
Ultrashort dark solitons interactions and nonlinear tunneling in the modified nonlinear Schrödinger equation with variable coefficients
N. M. Musammil, K. Porsezian, K. Nithyanandan +2
We present the study of the dark soliton dynamics in an inhomogenous fiber by means of a variable coefficient modified nonlinear Schrödinger equation (Vc-MNLSE) with distributed di…
Modulation instability in quasi two-dimensional spin-orbit coupled Bose-Einstein condensates
S. Bhuvaneswari, K. Nithyanandan, P. Muruganandam +1
We theoretically investigate the dynamics of modulation instability (MI) in two-dimensional spin-orbit coupled Bose-Einstein condensates (BECs). The analysis is performed for equal…
