On the evaluation of the ac-Stark shift and Kramers-Heisenberg dispersion formula
R. Radhakrishnan, Ramesh Babu Thayyullathil
We describe a unified approach for the determination of ac-Stark correction and Kramers-Heisenberg dispersion formula. In both cases the contribution from infinite intermediate sum…
Shape-changing Collisions of Coupled Bright Solitons in Birefringent Optical Fibers
M. Lakshmanan, T. Kanna, R. Radhakrishnan
Wecritically review the recent progress in understanding soliton propagation in birefringent optical fibers.By constructing the most general bright two-soliton solution of the inte…
Coupled nonlinear Schrodinger equations with cubic-quintic nonlinearity: Integrability and soliton interaction in non-Kerr media
R. Radhakrishnan, A. Kundu, M. Lakshmanan
We propose an integrable system of coupled nonlinear Schrodinger equations with cubic-quintic terms describing the effects of quintic nonlinearity on the ultra-short optical solito…
Suppression and Enhancement of Soliton Switching During Interaction in Periodically Twisted Birefringent Fiber
R. Radhakrishnan, M. Lakshmanan
Soliton interaction in periodically twisted birefringent optical fibers has been analysed analytically with refernce to soliton switching. For this purpose we construct the exact g…
