Abstract

In this paper, the authors present from theoretical point of view a comparison between two types of photonic logical circuits based on nonlinear optics phenomena. The linearly polarized light after two orthogonal directions is used for information processing by both types of photonic logical circuits. In first type of circuit at the each logical gate the input signals are amplified to a certain power value. In second type of circuit we assume that the power of signals can not be smaller than approximately 55% of the biggest signal power. This second type of circuit can be used in the circuits where it is well to know the losses, where the signal don't propagate on very long distances, in other words they can be used in good quality circuits where it is sure that the power of any signals can not be smaller than approximately 55% of biggest power of signal. The advantages of photonic logical circuits presented there are: the output signal is amplified to a certain value of power, they have a strong decidability, there are fast (switching time of photonic devices is about 10^-12- 10^-14s), the light signal remains all the time into optical domain etc.
