FIG. 1.

Light travels through the system via the cantilever that also acts as a waveguide and it is collected in the opposite side.

Image of FIG. 2.
FIG. 2.

Different regions with their respective refractive indices that the light travels through.

FIG. 3.

When the medium between the cantilever waveguide and the output waveguide is water (or buffer solution) instead of air, the optical output is increased due to the reduced refractive index difference.
