Abstract
An embodiment sensor includes a hybrid waveguide. The hybrid waveguide includes a first dielectric optical waveguide lying on and in contact with a dielectric support layer; a first surface waveguide optically coupled to the first dielectric optical waveguide, parallel to the first dielectric optical waveguide, and lying on the dielectric support layer. The first surface waveguide has a lateral surface configured to guide a surface mode. The hybrid waveguide includes a cavity intended to be filled with a dielectric fluid, separating laterally the first dielectric optical waveguide from the lateral surface of the first surface waveguide.
