Title
Refractive index measurements using an integrated Mach-Zehnder interferometer
Abstract
In this paper a refractometer system with an integrated optical sensor is presented. The sensitive element is a single or multichannel Mach-Zehnder interferometer (MZI) fabricated on silicon using waveguides made from SiO2, and SiON. The refractometer allows for real time monitoring of refractive indices of gases and liquids in an index range between 1 and 1,49 using the silicon MZI as a low cost consumable part.
