Abstract

Theory shows that with a suitable choice of the wavelengths of two pumps, and two signals about the zero-dispersion wavelength of a fiber, simultaneous unit conversion efficiency from one signal to the other, and vice versa, can be obtained. We have demonstrated near-complete wavelength exchange between two signal wavelengths, with two 200 mW pumps at 1544.94 and 1551.06 nm, in a 1-km-long highly-nonlinear dispersion-shifted fiber. This novel optical phenomenon may provide new functionality for optical networks.
