Controllable managements on the optical vector breathers in a coupled fiber system with multiple time-dependent coefficients

In this paper, chief attention is focused on a coupled optical fiber system governed by coupled Schrödinger-like equations which include five time-dependent coefficients. The optical vector breather solutions are obtained via symbolic iteration technique. Based on the solutions, the controllable managements of the optical breathers are investigated analytically via choosing the free coefficients, and adjusting the parameters involved. The results discover that various time-dependent boundary conditions will affect the optical pulse propagations in profiles.
