Solitons on demand.
‘We demonstrate solitons that are stable in a ring laser and form spontaneously with tuning laser bias, eliminating the need for an external optical pump.
A soliton is a self-reinforcing solitary wave that maintains its shape and travels at a constant speed.
Free-running stable optical dissipative solitons, called Nozaki–Bekki solitons, are created in a ring semiconductor laser; their spontaneous formation with tuning of laser bias eliminates the need for an external optical pump.
