Paper Abstract

In this paper, the authors present a comparison between two types of photonic logical circuits. Both of them there are based not only interference but also birefringence phenomena. The main device is the double-slit interferometer. In first version of circuit the output of logical gate is in the place where the central maximum interference is. We consider that there is signal to the output of logical gate only when the interference phenomenon appears. In second version of circuit the output of logical gate is in the place where the first minimum interference is. We consider that there is signal to the output of logical gate only when the interference phenomenon doesn't appear. Both types of circuits can be implemented not only in the integrated optics but also in the classic optics (where the laser beam is propagated through air). There are immune to electromagnetic fields and to any type of radiation. The light signal remains all the time into optical domain in both versions of photonic circuits. They are fast. The speed of the information transfer is limited only by the speed of light through the respective medium.
