“…3 for the unbalanced dual loop configurations. Although the phase noise values of both unbalanced and Vernier schemes are, in principle, not comparable to those reported for high-performance ultra-low phase noise OEOs [11], they can be significantly reduced by using low-residual phase noise components and by reducing the optical losses and thus suppressing the need for optical amplifiers. In the particular case of the Vernier OEO, we can furtherly contribute to diminishing the phase noise level by increasing the MCF length.…”

We report the first experimental demonstration of multi-cavity optoelectronic oscillators where the different cavities are hosted in a single multicore fiber. Different configurations are implemented on the same 20-m 7-core fiber link, exploiting both unbalanced dual-cavity operation (loop lengths are a multiple of a reference value) and multi-cavity Vernier operation (loop lengths are slightly different).

“…Although the phase noise values of both unbalanced and Vernier schemes are, in principle, not comparable to those reported for ultra-low phase noise OEOs [11], they can be reduced by using low-residual phase noise components (RF amplifiers and photodetectors) and by reducing the optical losses and thus suppressing the need for optical amplifiers. In addition, the phase noise performance can be improved if we use a laser with lower RIN and higher optical power, a Mach-Zehnder modulator with a lower V π value or a photodiode with better responsivity [11]. Although the use of 1-nm-bandwidth optical filtering reduces the ASE noise induced by the EDFAs, we still observe a considerable noise level.…”

We report, for the first time to our knowledge, the experimental demonstration of multi-cavity optoelectronic oscillators where the cavities are provided by the different cores of a multicore fiber. We implemented two multi-cavity architectures over a 20-m-long 7-core fiber link: unbalanced dual-cavity oscillation (the cavity lengths are a multiple of a reference value) and multi-cavity Vernier oscillation (the cavity lengths are slightly different). Since all the cavities are hosted under a single fiber cladding and are subject to the same environmental and mechanical conditions, optoelectronic oscillators built upon multicore fibers benefit from improved performance stability as compared to independent singlemode fiber cavities.

“…In essence, a short loop provides the required spectral separation between adjacent oscillating modes while a long loop is responsible for the spectral purity. The number of loops can as well be generalized to an arbitrary number [54][55][56][57]59]. In concrete, the work reported in [54] experimentally demonstrated three-cavity OEOs by using three different single-mode fiber links whose lengths were multiple of a given reference value.…”

“…Multicavity or multiloop optoelectronic oscillators [53][54][55][56][57] can benefit from a reduction of size and weight if the different cores of a multicore fiber act as the required oscillation cavities. In addition, since all the cavities are hosted within the same cladding, this approach provides a fiber integrated medium for enhancing the OEO relative stability against environmental and mechanical fluctuations.…”

Abstract:We review the introduction of the space dimension into fiber-based technologies to implement compact and versatile signal processing solutions for microwave and millimeter wave signals. Built upon multicore fiber links and devices, this approach allows the realization of fiber-distributed signal processing in the context of fiber-wireless communications, providing both radiofrequency access distribution and signal processing in the same fiber medium. We present different space-division multiplexing architectures to implement tunable true time delay lines that can be applied to a variety of microwave photonics functionalities, such as signal filtering, radio beamsteering in phased array antennas or optoelectronic oscillation. In particular, this paper gathers our latest work on the following multicore fiber technologies: dispersion-engineered heterogeneous multicore fiber links for distributed tunable true time delay line operation; multicavity devices built upon the selective inscription of gratings in homogenous multicore fibers for compact true time delay line operation; and multicavity optoelectronic oscillation over both homogeneous and heterogeneous multicore fibers.
