Ha. Haus et al., CONTINUUM GENERATION BY PERTURBATION OF SOLITON, Journal of the Optical Society of America. B, Optical physics, 14(2), 1997, pp. 304-313
Lumped perturbations of a soliton, such as gain, filtering, and amplit
ude and phase modulation, are considered. A new formalism is developed
to compute the continuum generated by these perturbations through the
use of adjoint functions. An exact expression for the continuum in th
e far field is obtained. (C) 1997 Optical Society of America.
