All optical logic gates are the key elements of contemporary optical computing unit. For that non-linear attribute of reflective semiconductor optical amplifier (RSOA) is exploited to configure optical logic gates. Accordingly, in the manuscript all optical OR/NOR/Buffer binary logic network for the nonreturn to zero format has been designed. Its operation at 100 Gbps data rate has been successfully realized. For the applied data inputs in nonreturn to zero patterns, their corresponding output waveforms for the stated logic action have been verified. Numerical investigations for the imperative design constraints as data rate, injected power and imperative elements of the semiconductor optical amplifiers (SOAs) pump current, carrier density, active length, confine factor, laser power has been appropriately executed with optimum performance. It has depicted good extinction ratio (&gt;10 dB) performance with confine factor more than 0.2 and higher carrier density of amplifier. Further, it also accomplished, that for the OR, buffer logic execution with lower power of pump laser and for the NOR logic execution higher power laser pump source is required. The proposed design could fulfill need for the impending higher data rate composite optical computing units.
