Abstract :
We consider the origin of frequency-doubling in single-mode optical fibres. We show that the presence of nonlinear electric quadrupole and magnetic dipole moments can explain the initial formation of frequency-doubled light, and present the results of a detailed theoretical analysis of these effects which is in good agreement with experiment.
