Integrated Mid-IR Waveguide Sensor for Laser Based Trace Analysis in Aqueous Solutions

Not Accessible

Your library or personal account may give you access

Abstract

An in-line sensing platform for detecting contaminants in aqueous solution is presented, comprising Ge waveguides, microlenses and grating couplers for rapid interfacing with mid-IR spectrometers, and a hydrophobic mesoporous layer for selectivity toward apolar contaminants.
