The prospects of using optics in computing rely mostly on high parallelism and broad bandwidths of optical systems. A high parallelism is more efficient in analog systems (such as Fourier spectrum analyzers and correlators), and broad bandwidths can be used for digital systems that operate with short pulses. One of the most interesting ideas is to use the nonlinear phenomena in optical fibers. These phenomena are self- and cross-phase modulation (the Kerr effect), soliton dragging, and stimulated Raman scattering. This report gives a state-of-the-art review of applications of nonlinear phenomena in optical fibers.
