Design and Performance Analysis of All-Optical Reversible Full Adder, as ALU

This manuscript is an attempt to design all-optical reversible arithmetic logic unit. Reversibility will not only help in reducing the errors at the receiving end, but also will increase the multitasking of the optical processors by reducing heat dissipation. At the receiving end of an optical network, conversion of data from optical to electrical takes place for the processing purpose. This kind of processing of data dissipates huge amount of energy in form of heat. This problem can be solved by developing optical processing unit. This manuscript proposed the solution for above-said problem. This kind of processors will simplify the processing by eliminating optoelectronic conversion, but it will also minimize the problem of heat dissipation. The value of average quality factor for this proposed model is 59.98 dB, while the average extinction ratio is 21.26 dB. Optical cost for this proposed model is 4.
