Photonic processing of ultra wide band signals to mitigate interference and to improve efficiency

Abstract

UWB signal generation in optical domain is an emerging technique and finds immense advantages due to the elimination of complex optical-electrical and electrical-optical conversion devices. The generated UWB finds application in short range communications, offering advantages of high bandwidth and low power consumption. Satisfying these intentions, this paper provides the generation of Ultra Wide Band signals using photonic processing techniques. In this paper, the generation of reconfigurable highorder UWB signals using semiconductor optical amplifier and a Mach-Zehnder modulator (SOA-MZM) structure is demonstrated. The generation technique is compact, simple, and requires only a single wavelength input. UWB signal of higher orders is generated from the scheme.
