Optical pulse propagation

摘要

A method of optical pulse propagation via a dispersive optical fibre 110, the method comprising the steps of: launching the optical pulses into the fibre at a pulse intensity sufficient to provide non-linear dispersion compensation during propagation through a first portion of the fibre 110; and providing a counter-chirping device 140 to substantially compensate for the dispersion of a remaining, second portion of the fibre 110.
