High Q Si Slot Waveguide Ring Resonators for Gas Sensing Application

Not Accessible

Your library or personal account may give you access

Abstract

We fabricated Si slot waveguide ring resonators having Q factor of 2.5×104. Based on the resonance characteristics, refractive index sensitivity Δn of 1×10−5 was theoretically estimated by the difference of transmitted optical intensity at the resonance wavelength.
