摘要：

A passive integrated optical waveguide refractometer 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 Delta n=1.3x10(-5). (C) 1997 American Institute of Physics.
