Stable and compact dual-loop optoelectronic oscillator using self-polarization-stabilization technique and multicore fiber

We experimentally demonstrate a stable and compact dual-loop optoelectronic oscillator (OEO) using multicore fiber and self-polarization-stabilization technique. Two fiber cavities using two standard single mode fibers with different length in traditional dual-loop OEOs are replaced by only one multicore fiber where several cores are linked together to form the short and the long cavity simultaneo...
