In the contemporary world there is enormous hike in communication engineering applications, outcome with massive heat dissipation from the processing nodes. So energy efficient information network is one of paramount issue nowadays. For that optical reversible computing could be a landmark with base as optical logic gate. Reduction in power dissipation, consumption could be accomplished through a blend of reversible and irreversible optical processing and the nodes may recuperate the data. Accordingly, in this article two designs with semiconductor optical amplifier, used as Mach–Zehnder interferometer based all optical reversible Feynman gate, irreversible AND logic gate within a single photonic circuit has been proposed. The output waveforms for AND logic operation, Feynman logic the P (data output identical to input), Q (A ⊕ B) has been verified at 100 Gbps data rate. The designs have been evaluated on the basis of key parameter extinction ratio factor. Numerical simulations have inferred excellent ER performance with design-2(ER&gt;13 dB) in contrast to design-1(ER as 10.2 dB). Performance evaluations for significant deign parameters as pump current, length, width, carrier transport, confine and current injection factor yielded excellent performance. This evaluation could be an assist toward design of contemporary optical networks.
