Abstract :
This paper presents a study on asymmetric slot waveguide resonators to be used as sensing elements in Laboratory on a chip (LOC). They combine slot waveguide high sensitivity and advantages, with improved resonator performance due to enhanced mode matching in racetrack bends. Depending on target bio-molecules, asymmetric slot resonators are very promising for small molecule sensing (dimensions <; 200nm), maximizing their interaction with the optical field used for sensing.
