Abstract
A photonic interconnection elementary switch is integrated in an optoelectronic chip/The switch includes first and second linear optical waveguides which intersect to form a first intersection. Two first photonic redirect ring resonators are respectively coupled to the first and second optical waveguides. Two second photonic redirect ring resonators are respectively coupled to the first and second optical waveguides. A third linear optical waveguide is coupled to one of the first ring resonators and one of the second ring resonators. A fourth linear optical waveguide is coupled to another of the first resonators and to another of the second ring resonators. A base switch, complex switch, and photonic interconnection network integrated in an optoelectronic chip, include at least two of the photonic interconnection elementary switches.
