摘要：
We report the fabrication and the characterization of an integrated optofluidic Mach-Zehnder interferometer based on liquid core waveguides. The light is confined inside a low refractive index liquid core by antiresonant reflecting optical waveguide. Several asymmetric Mach-Zehnder interferometers have been realized with standard silicon technology. An optical characterization of the devices has been carried out by measuring the spectrum of optical transmitted intensity from two different Mach-Zehnder configurations. The results show that interferometers with a good visibility can be achieved in good agreement with the theoretical results. (c) 2008 American Institute Of Physics.
