The fiber exhibits a number of features that make it extremely
attractive for use in optical information processing systems. Among
them are the huge bandwidths and high efficiencies of nonlinear pile-
nomena achieved at relatively low powers of laser radiatioui. In addi
tion, the problem of overheating is obviated here because heat is
removed through fairly large lateral surfaces.
The systems suggested so far rely on two nonlinear rfiechanisms.
The principles of the use of SRS were discussed in /1-3/. Prom the
estimates, the pulse repetition frequency in the SRS-device can be
as high as io12 Hz for pulse energies of i012 A variety
of logic elements operating through light-induced refractive-index
variations were also suggested /4-6/. They provide the pulse repetition frequencies up to 1013-i014 Hz.
Lu this paper we discuss different versions of optical signal
processinF systems.
