All-fiber ultralow-energy soliton management at 1.55 µm
Abstract
A highly nonlinear photonic-crystal fiber (PCF) is shown to enable an efficient coupling of a low-energy picosecond output of an erbium fiber laser into optical solitons. With this fiber, stretched 2.2 ps, 1.2 nJ, 1.55 µm pulses of an erbium fiber laser can be coupled into sub-100 fs optical solitons with an energy slightly below 1 nJ. The peak power and the pulse width of these solitons can be finely tuned by pulse chirp management in a variable-length single-mode fiber, connected to the erbium fiber laser output and cascaded with the PCF.
