Frequency-Sextupling Optoelectronic Oscillator Using a Mach–Zehnder Interferometer and an FBG


A frequency-sextupling dual-loop optoelectronic oscillator (OEO) without any electronic microwave filters is proposed and demonstrated. Within the proposed OEO, a modulated signal that consists of an optical carrier and odd-order sidebands is generated employing a Mach–Zehnder interferometer (MZI). The modulated signal is then divided into reflection elements and transmission parts by a fiber Bragg grating (FBG). The reflection components, including the optical carrier and therefore the ±1st-order sidebands, are sent to a photodetector (PD1) and then fed back to the MZI to make the OEO loop. The transmission elements, together with the ±third-order sidebands, are sent to a different PD (PD2) to come up with a frequency-sextupled microwave signal. Meanwhile, a microwave photonic filter is made by the joint operation of the MZI, the FBG, and an optical domain dual-loop composite cavity that performs the choice of the oscillation mode. Therefore, a elementary oscillation signal at 4.03 GHz and its frequency-sextupled microwave signal at twenty four.eighteen GHz are generated with their performance being evaluated.
