Paper Abstract

Effect of nonlinear polarization rotation in birefringent optical fiber was used to distinguish the different levels of incident optical beams. This effect was employed to design all-optical switching and routing devices for processing of bit word streams and optical polarization transistor to amplify optical pulses. These devices can be used to perform summation and multiplication of binary words. Serial and parallel representation of the bit words discussed from the point of view bit flow architecture of optical computers. A method of time distributed parallel representation of the bit words is proposed. It is shown that this representation permits to obtain such form of the result that the beginning of the result may be used in further computations before the previous computation is completed. Thus, in spite of the fact that the whole process of multiplication of two N-bite words required 2N time steps of computation, the delay between receiving the beginning of the input words and sending the beginning of the result to the next processor is only one time step. The performance of all-optical computer may be improved by the use of extremely short femtosecond optical pulses. In this case, nonlinear effects can compensate the dispersion broadening of the optical pulses and soliton regime of propagation is achieved. Nonlinear interaction between the optical solitons with orthogonal polarization permits to perform high- performance computations.
