Label-Free Biosensing With a Slot-Waveguide-Based Ring Resonator in Silicon on Insulator
We present a slot-waveguide-based ring resonator in silicon on insulator (SOI) with a footprint of only 13 mum times 10 mum, fabricated with optical lithography. Experiments show that it has 298 nm/RIU sensitivity and a detection limit of 4.2middot10<sup>-5</sup> RIU for changes in the r...
