Abstract

We present a slot optical waveguide ring resonator that can be used as a refractive index sensor. The proposed ring resonator works on the principle of coupling of the mode from the bus waveguide to the ring waveguide. The ring resonator was analyzed using the finite-difference time-domain method. Our proposed waveguide structure showed a sensitivity of 42 nm/RIU. Our aim is to design a chalcogenide ring resonator for refractive index sensing in midinfrared wavelengths.
