Abstract
The optical mode of a photonic device is coupled between a first region made of a semiconducting material, and a second region made of a dielectric material. Photons are generated within the first region, while the optical mode is predominantly stored within the second region. The thickness of the first region and its width are controlled to determine its effective refractive index, enabling control of the optical mode.
