Narrow line width frequency comb source based on an injection-locked III–V-on-silicon mode-locked laser [PDF]
Optics Express, 2016 In this paper, we report the optical injection locking of an L-band (similar to 1580 nm) 4.7 GHz III-V-on-silicon mode-locked laser with a narrow line width continuous wave (CW) source. This technique allows us to reduce the MHz optical line width of the

Breather Molecular Complexes in a Passively Mode‐Locked Fiber Laser [PDF]
Laser & Photonics reviews, 2021 Breathing solitons are nonlinear waves in which the energy concentrates in a localized and oscillatory fashion. Similarly to stationary solitons, breathers in dissipative systems can form stable bound states displaying molecule‐like dynamics, which are ...
