Photon-number fluctuation and correlation of bound soliton pairs in mode-locked fiber lasers

Photon-number fluctuation and correlation of bound soliton pairs in mode-locked fiber lasers.

Quantum photon-number fluctuation and correlation of bound soliton pairs in mode-locked fiber lasers are studied on the basis of the complex Ginzburg-Landau equation model. We find that, depending on their phase difference, the total photon-number noise of the bound soliton pair can be larger or smaller than that of a single soliton, and the two solitons in the soliton pair have a corresponding...

Quantized separations of phase-locked soliton pairs in fiber lasers.

We report the discovery of a quantization of the separation between phase-locked soliton pairs that is related to the radiation waves known as Kelly sidebands, in a passively mode-locked fiber ring laser. Our numerical simulations that predict this phenomenon have been confirmed by our experimental results.

Mode Locked Fiber Lasers

Mode-locked ytterbium fiber lasers.

A compact fiber laser is demonstrated with use of a Gires-Tournois compensator and a short length (2-4 cm-long) of highly doped ytterbium (Yb) fiber providing net anomalous group-velocity dispersion. With use of a novel semiconductor saturable absorber mirror based on GaInNAs structure, self-started 1.5-ps-pulse mode-locked operation was obtained at 1023 nm with a repetition rate of 95 MHz. A m...

Discrete Set of Separations between Phase-Locked Soliton Pairs in a Passively Mode-Locked Fiber Laser

Passively mode-locked fiber ring lasers and dispersion-managed fiber transmission links are examples of optical dissipative dynamical systems, supporting stable pulses and multi-soliton trains. An example of stable multi-soliton solution with +/-p/2 phase differences, have been predicted theoretically earlier based on the model of complex quintic Ginzburg-Landau equation [1]. More recently, we ...
