Demonstration of wavelength exchange in a highly-nonlinear fiber

A near-complete wavelength exchange between two signal wavelengths were demonstrated with two 200 mW pumps at 1544.94 nm and 1551.06 nm, in a 1 km-long highly-nonlinear dispersion-shifted fiber. Theoretically it was shown 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 could be obtained. The design of novel optical devices, with functions of wavelength exchanger, optical cross connect switch and time-division multiplexer was possible with the research.link_to_subscribed_fulltex
