Beam propagation in an active nonlinear graded-index fiber
Anuj P. Lara, Samudra Roy, Govind P. Agrawal
A theoretical model is developed by exploiting the variational technique to investigate the evolution of an optical beam inside an optically pumped graded-index fiber amplifier. Th…
Femtosecond Pulse Trains through Dual-Pumping of Optical Fibers: Role of Third-Order Dispersion
Aku Antikainen, Govind P. Agrawal
Generation of high-repetition-rate, femtosecond, soliton pulse trains through dual-wavelength pumping of a dispersion-decreasing fiber is studied numerically. The achievable shorte…
Lossless Suppression and Enhancement of Soliton Self-Frequency Shifts
Francisco R. Arteaga-Sierra, Aku Antikainen, Govind P. Agrawal
Soliton self-frequency shifts (SSFS) can be suppressed in optical fibers through spectral recoil, but this process leads to losses through continuous transfer of energy to a disper…
Perturbed Dissipative Solitons: A Variational Approach
Ambaresh Sahoo, Samudra Roy, Govind P. Agrawal
We adopt a variational technique to study the dynamics of perturbed dissipative solitons, whose evolution is governed by a Ginzburg--Landau equation (GLE). As a specific example of…
