Tree-net architecture for integrated all-optical arithmetic operations and data comparison scheme with optical nonlinear material

In the field of optical interconnecting network the tree architecture has already taken the significant roles. Nonlinear optics has drawn a great interest in all-optical signal processing for its high speed photonic activity. Optical nonlinear materials (ONLM) may provide a major support to optical switching-based all-optical logic and algebraic operations. Here operational speed is extremely high (far above GHz). In this paper, an ONLM-based switching system is extensively used to design tree architecture for developing some arithmetic operational system in an all-optical domain. An alternative scheme of all-optical addition and subtraction and comparison of binary data is also proposed exploiting the above optical tree.
