Abstract: A ring resonator electro-optical device includes a first silicon nitride waveguide and a second annular silicon waveguide that comprises a first section running under a second section of the first waveguide. The second waveguide also includes an annular silicon strip having a cross-section increasing in the first section from a minimum cross-section located under the second section.

Abstract: A photonic interconnect switch is formed by first and second linear optical waveguides that cross to form an intersection. First and second redirecting photonic ring resonators are coupled together in an intermediate optical coupling zone and are controllable with an electrical signal. The first ring resonator is coupled to the first optical waveguide in a first optical coupling zone. The second ring resonator is coupled to the second optical waveguide in a second optical coupling zone.
