Photonic logic gates with simultaneous processing of multiple signals

摘要

In this paper, the authors present, from theoretical point of view, some photonic logic gates based not only interference but also birefringence phenomena. An important advantage of these gates is the possibility of simultaneous processing of multiple light signals, with different light wavelengths, using a single logic gate. The presented photonic logic gates have many other advantages: they are fast, they are immune to electromagnetic fields, they can be use both in integrated photonics and in classical optics, the light signal remains all the time into optical domain etc.
