Design and Investigations with all Optical Multilogic Network

Abstract

Abstract This article presents investigation for all optical multilogic function in the proposed single photonic network. Logic operations the AND, OR, NOR, XNOR, NOT, Buffer, A ˉ B $\bar AB$ , A B ˉ $A\bar B$ have been executed simultaneously at higher data rate for nonreturn-to-zero pattern on the different C-band wavelengths. Numerous logic functions have been accomplished by the optical multiplexer, couplers exploiting SOA nonlinearities, which are else contemplated as cons, if SOA is exercised as an amplifying device. Numerical simulation for parameters as bias voltage of the modulator, nonreturn-to-zero, return-to-zero, Mach-Zehnder type modulation formats, data rate and numerous drives as on-off-ramp, raised cosine, on-off-exp, on-off in conjunction with key design features length, width, thickness of SOA have been aptly explored in terms of the extinction factor. Investigations depicted good performance for the nonreturn-to-zero format. Accordingly, output patterns for the multilogic executions have been verified at 10 Gbps data rate with nonreturn-to-zero pattern. The proposed schematic could be one of the feasible means for the design of upcoming composite photonic computation higher data rate links, as it excludes need for most expensive optoelectronic translations.
