Design of Ultrafast Optical Full Subtractor Link and Performance Analysis

Abstract

Abstract
This article illustrates proposed optical full subtractor schematic through SOA-MZI, yield borrow and difference outputs concurrently. The objective has been accomplished by exploiting nonlinear attributes with SOA. Numerical simulations have been executed and craving optical subtractor output waveforms have been verified at 100 Gbps data rate. Optimization criterion for the design’s performance measurement is taken as Q-factor and the extinction ratio factor. The subtractor output difference and borrow outcomes with excellent performance metric, depicted Q, extinction factor over 12 dB. Enormous design issues have been aptly explored here and designed subtractor link has been efficiently visualized. Investigations have been carried out pro numerous key constituents of the design as variation in the data rate, pump current, active length, width, thickness, carrier transport factor, reflectivity of the SOA as well for the modulator bias voltage, peak laser power, wavelength and attenuation factor, depicted excellent performance for the established link. This projected schematic is simpler and presumed to have ability of higher order integration, as well supportive for the forthcoming higher data rate composite all optical signal processing units and imparting enormous benefits excluding extensive optoelectronic conversions.
