We develop graphical representations of the noise characteristics imposed on initially coherent light by the process of self-phase modulation in an optical fibre. The graphical methods provide physical understanding of the squeezing that sets in at the shorter propagation distances, and the subsequent desqueezing that occurs as the distance of propagation is increased. They also provide quantitative agreement with the results of the quite complicated analytical theory of self-phase modulation.

A simple method for the production of ultrashort light pulses (USPs) with suppressed photon fluctuations is considered, which is based on self-phase modulation (SPM) of a USP in a nonlinear medium, say, an optical fibre and subsequent transmission of a pulse through a dispersive optical element.
