Abstract

A passive integrated optical waveguiderefractometer based on bendloss changes in a spiral-shaped channel waveguide is proposed and fabricated in Si3N4/SiO2 technology. The experimentally determined performance and the theoretical predictions, based on a simple model for so-called “whispering gallery modes,” agree very well. The minimum detectable refractive index change was measured to be Δn=1.3×10−5.
