Abstract: Force-induced long-period fiber gratings are formed in a graded-index two-mode fiber and a step-index two-mode fiber in series to build an all-fiber bandpass filter. The passband transmittance and bandwidth in the filter response are refined… read more here.

DOI: 10.1364/oe.474238
Abstract: We investigate the modal energy flow of the femtosecond-pulsed beam self-cleaning on LP11 mode with the influence of different factors such as the initial fraction of LP11 mode, initial peak power, distribution of high-order modes… read more here.
