Integrated refractive index sensor using silicon slot waveguides

Applied Optics, 2017
We propose an integrated refractive index (RI) sensor based on evanescent field absorption (EFA) within a silicon slot waveguide, where the RI variation is translated into a varied attenuation coefficient and eventually the output power at the end of the waveguide.
