Abstract
A photonic integrated circuit includes an optical coupling device situated between two successive interconnection metal levels. The optical coupling device includes a first optical portion that receives an optical signal having a transverse electric component in a fundamental mode and a transverse magnetic component. A second optical portion converts the transverse magnetic component of the optical signal into a converted transverse electric component in a higher order mode. A third optical portion separates the transverse electric component from the converted transverse electric component and switches the higher order mode to the fundamental mode. A fourth optical portion transmits the transverse electric component to one waveguide and transmits the converted transverse electric component to another waveguide.
