Abstract
An optical waveguide is configured to propagate a light signal. Metal vias are arranged along and on either side of a portion of the optical waveguide. Additional metal vias are further arranged along and on either side of the optical waveguide both upstream and downstream of the portion of the optical waveguide. The metal vias and additional metal vias are oriented orthogonal to a same plane, the same plane being orthogonal to a transverse cross-section of the portion of the optical waveguide.
