An RF photonic link having at least one light source, at least one photodetector, multiple optoelectronic modulators, and an RF waveguide common to each one of said multiple optoelectronic modulators. The multiple optoelectronic modulators are optically arranged in parallel to receive light from said at least one light source and are disposed in said RF waveguide. The RF waveguide, in use, guides an RF electromagnetic field applied to each of the multiple optoelectronic modulators disposed therein, the RF electromagnetic field propagating through the RF waveguide in a direction that is perpendicular to a direction in which an optical field propagates through each of said optoelectronic modulators.
