Abstract: An elementary photonic interconnect switch is integrated into an optoelectronic chip and includes four simple photonic interconnect switches. Each simple photonic interconnect switch has two optical waveguides that cross and are linked by a ring resonator having one ring. A basic photonic interconnect switch, a complex photonic interconnect switch and/or a photonic interconnect network are integrated into an optoelectronic chip and including at least two elementary photonic interconnect switches.

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.
