Abstract:This article presents an analysis of an electro-optical up-converter relying on a semiconductor optical amplifier Mach–Zehnder interferometer (SOA-MZI). The pulsed control signal is generated by an optical pulse clock (OPC) with a repetition rate of fs= 19.5 GHz. The intermediate frequency (IF) signal, which carries the modulation format known as quadratic phase shift keying (QPSK) at a frequency fIF, is shifted at the output of the SOA-MZI to high outlet mixing frequencies nfs±fIF, where n represents the harm… Show more
“…The Mach-Zehnder Interferometer implemented on a silicon platform stands out as a pivotal element for various applications, ranging from telecommunications (used in photonic waveguide switches, and photonic modulators) to sensing, neural networks, quantum and signal processing [3][4][5][6][7][8][9][10][11]. The utility of the MZI stems from its interferometric property, and this is achieved by creating a relative phase shift between both arms of the MZI.…”
This article presents a demonstration of the interferometric characteristics inherent in an unbalanced Mach-Zehnder Interferometer (MZI), implemented on a silicon-on-insulator platform through precision fabrication techniques. The investigation delves into the intricate relationship between the free spectral range (FSR) and various lengths of unbalanced MZIs. Notably, a comparison between simulation and experimental outcomes reveals a remarkable agreement.
