Paper Abstract

The ideology of a photonic crystal resonator covered with optically nonlinear layers is proposed for binary adder and logic gates of various kinds. The all-optical way to transform a physically added sequence of signals into the logical sequence with corresponding shift of digital units is based on the nonlinear band shift effect. In this work, the electromagnetic field structure for optically linear 1D porous silicon photonic crystal is investigated. The optical parameters of a 1D photonic crystal resonator built on layered porous silicon covered with a nonlinear layer are calculated for various nonlinear materials. An approximate design of an all-optical adder based on 1D porous silicon resonator is considered. The adder heating by powered optical pulses and energy distribution inside the device are analyzed and the problem solution with the use of special semitransparent redirecting mirrors is proposed. It was found that from the point of view of heating the R-scheme of signal processing is more optimal.
