Emergence of self-organized long-period fiber gratings in supercontinuum-generating optical fibers

Opt Lett. 2009 Mar 1;34(5):668-70. doi: 10.1364/ol.34.000668.


A localized long-period fiber grating emerges in a silica optical fiber transmitting femtosecond pulse-induced supercontinuum. Simultaneously, a specific higher-order fiber cladding mode associated with the grating gains amplification at the expense of the fiber core mode. The grating has a period dependent on the dielectric structure of the fiber and is therefore classified as a self-organized structure.
