Nano photonic and ultra fast all-optical processing modules.
In this paper we present an all-optical approach allowing the realization of logic gates and other building blocks of a processing unit. The modules have dimensions of only few microns, operation rate of tens of Tera Hertz, low power consumption and high energetic efficiency. The operation principle is based upon construction of unconventional wave guiding nano-photonic structures which do not include non-linear materials or interactions. The devices developed and presented in this paper include logic diffractive phase detector, generalized diffractive phase detector, logic gates as AND, OR and NOT, amplitude modulator and analog adder/subtractor.
