in the transmitted medium. These results confirm both theoretically and experimentally the potential of this approach where the grating is probed through the substrate bottom. Further development will aim to leverage this optical energy transfer at the two crossing angles for sensing application such as detection of gaseous species. This topic will be addressed in a forthcoming article where its performances will be evaluated( sensitivity, optical losses...). Another point to consider is the possibility of avoiding the use of the half sphere to couple light in the resonant structure, in order to reduce aberrations and to propose a compact and miniaturized optical sensor.
