Mid infrared waveguide spectroscopy for cocaine detection in liquid environments
2012
Proceedings of the EOS Annual Meeting
A germanium strip waveguide on a silicon substrate is integrated with a microfluidic chip to detect cocaine in tetrachloroethylene solutions. In the evanescent field of the waveguide, cocaine absorbs the light at 5.8μm, which is emitted from a quantum cascade laser. The lowest measured concentration is 100μg/ml.
