A new optical computing experimental system is presented. Designed based on tri-valued logic, the system is built as a photoelectric hybrid computer system which is much advantageous over its electronic counterparts. Say, the tri-valued logic of the system guarantees that it is more powerful in information processing than that of systems with binary logic. And the optical characteristic of the ...

The ability to coherently store and retrieve optical information in a rapidly tunable manner is an important ingredient for all-optical information processing. In the classical domain, this optical buffering is necessary to manage information flow in complex networks. In quantum information processing, such a system can also serve as a long-term memory capable of storing the full quantum inform...

An electro-optic tunable single and multi-channel optical filter based on one-dimensional defective photonic crystal (1DDPC) structure is proposed. A couple of externally tunable defects in arrangement of (AB)5D1(BA)D2(BA)5, where A and B are dielectric materials, D1 and D2 are the tunable defects are used. The defects are composed of the ferroelectric LiNbO3 crystals and two pairs of thin Ag l...
