Design of two-input nanophotonic AND/OR gate

摘要

In this paper, we report the dynamic behavior of two-input nanophotonic gate that works as an AND/OR gate at finite temperatures. Occupation levels of the proposed nanophotonic gate in the ON and OFF states under different values of temperature have been calculated. It is shown that when the gate operates as an AND gate, the output level occupation probability of the gate in the OFF (ON) state increases (decreases) with temperature. Hence, the ON/OFF ratio of the gate reduces with temperature. Also, it is shown that the output level occupation probabilities for the OR gate in the ON state decrease with temperature. As the output level occupation probabilities for this OR gate in either OFF state is equal to zero, the ON/OFF ratio for this gate is infinity. (C) 2014 Elsevier GmbH. All rights reserved.
