Photonic platform for finely controllable generation of multi-bound waves

摘要

This work studies a fibre laser platform for generation of controllable localised wave structures. It was found out that a figure-8 laser with two independently pumped active media allows precisely controllable generation of solitary-wave bound states of up to the 6th order. Nonlinear shortening of the temporal pulse separation was discovered when 3 or more bound pulses are generated. Shown are the peculiarities of transitions among pre-determined dissipative multi-soliton complexes occurring both with and without Raman wave generation. Provided are distribution maps of peak power and energy of stable bound waves depending on pump powers of the active media.
