Reconfigurable optical logic unit with a terahertz optical asymmetric demultiplexer and electro-optic switches

A reconfigurable optical logic unit that can execute any binary logic and arithmetic operation on the same hardware with different configurations is proposed. The design, based on cascaded terahertz optical asymmetric demultiplexer switches, introduces reconfigurability with the help of electro-optic switches. The model is simple and practicable.
