Generation of a 40-GHz pulse stream by pulse multiplication with a sampled fiber Bragg grating.
TL;DR: A sinc-sampled fiber Bragg grating is used to achieve multiplication of the repetition rate of a pulse stream from 10 to 40 GHz with spectral characteristics that ensure that the resultant pulses-solitons of 3.4-ps width-have the same individual pulse characteristics as those of the input.

Novel writing technique of long and highly reflective in-fibre gratings
Jean Martin,Francois Ouellette +1 more
TL;DR: In this paper, a novel method for writing fibre Bragg gratings is introduced, which consists of translating a UV beam along the fibre through a phase mask, and the phase mask and the fibre are held together, the phase of the interference pattern generated by the mask is not altered when the beam is translated along the mask.
