Feasibility of Cascadable Plasmonic Full Adder

The concept and configuration of a plasmonic cascadable full adder are proposed, whose logic operation is carried out by interference of surface plasmons and whose circuits are formed only with single- and multiple-mode plasmonic waveguides. This full adder is fabricated by patterning a SiO2 film deposited on a metal film using complementary metal-oxide-semiconductor-compatible processes except fo...
