Abstract

We propose a coupled-resonator-optical-waveguide-based sensor with multi-pixel detection using all-silicon sub-bandgap photodetectors at 1550 nm. Our proof-of-concept experiments of a PIN-diode-integrated three-microring CROW demonstrate sensing a minimum effective refractive index change of 2×10^-5.
