Long-period fiber gratings spontaneously written by a mechanism markedly different from Hill grating formation

[摘要]：Pumping a nonlinear germanosilicate fiber with intense near-infrared femtosecond laser pulses for supercontinuum generation may invoke multiphoton-assisted photosensitivity of glasses to write a long-period fiber grating. In sharp contrast to the spontane
