The switching of optoelectronics to full optical computing operations based on nonlinear metamaterials

The recent progress in optical computing outlines the fact that electronic computing has almost failed to cope with the international optical computation and communication traffic demand. Thanks to the non-linear material (NLM) which pave the way to new designs of new optical devices. A proposal for developing the most basic element in the optical computer such as optical switch, optical gates like OR gate, AND gate, XOR gate, flip-flops…. etc. has been introduced in recent research papers, also a proposal of the optical logic and arithmetic processor (OLAP) and the all-optical a-stable multi-vibrator has been introduced. Here some proposal developments are presented in this track, three components which they are most important in any new optical project those are optical switch, optical oscillator, and optical trap, the optical oscillator was introduced using an electro-optical modulator and, in this study, the oscillator design has no electro-optical elements, also the optical trap here works as an optical memory of binary data.
