Abstract
We present a new waveguided-sensing configuration combining the advantages of two effects, namely, two-wave interference and multiple-wave interference in a single sensing device. The sensor is accessed vertically from above by means of a three-port grating, and its readout can be accomplished both in an up-reflective or waveguided mode. The superposition of the two outcoming signals results in a variety of transmission characteristic curves depending on fabrication parameters, which are optimized in order to attain enhanced sensitivity. The sensor is analyzed by means of a simple scattering matrix model and confirmed by full FDTD simulations.
