Ultrashort Pulse Propagation Through Fibre Gratings: Theory and Experiment

Abstract

In-fibre Bragg gratings have numerous applications for optical communications and fibre optic sensors. Typically, grating-based devices and applications involve incoherent broadband sources, narrowband cw sources, or pulsed (quasi-cw) sources where the spectral bandwidth of the input pulse is narrower than that of the grating response. Propagation through fibre gratings for the above cases has been examined and is well understood.1,2
