AN EXACT SOLUTION TO THE SPATIAL EVOLUTION OF A CARRIER AND A PAIR OF SIDE-BANDS IN A CUBICALLY NONLINEAR MEDIUM

[摘要] The propagation of an amplitude modulated signal consisting of a carrier and a single side-band pair in a cubically nonlinear, nondispersive medium is solved exactly using the coupled mode approach. No approximation of undepletion is introduced. We show in the most general conditions the existence of a periodic exchange of energy between the carrier and the side-bands. Other forms of solutions are also found to exist. The steady state solution of the problem is necessarily introduced for a better understanding of the process of energy exchange.
