“…In MWP, the frequency up-conversion is a nonlinear process [8] where the lower RF frequency of a modulated signal is translated to a higher frequency optical signal by keeping its characteristics by means the photonic mixing. RF frequency conversion based on photonic mixing are of great interest on processing, analyzing and detections of signals in the radioover-fiber systems and many optical setups [9].…”

In order to perform photonic mixing and Radio Frequency (RF) generation by frequency up-conversion, the authors analyze the use of a single Semiconductor Optical Amplifier (SOA) and a Semiconductor Optical Amplifier-Mach-Zehnder Interferometer (SOA-MZI) structure by computer simulation using Advanced Design System (ADS) software. It assesses and compare both devices in terms of RF conversion gain and Cross Gain Modulation/Cross Phase Modulation (XGM/XPM) bandwidth. The simulations were carried out as function of several bias currents by mixing one and two optical input signals.Results have shown that SOA-MZI presents an average RF conversion gain 1 dB higher than single SOA.
