A Fabry-Perot Refractometer for Chemical Vapor Sensing by Solid-Phase Microextraction
The contour lithography method  is used to improve the fabrication yield of previously demonstrated  microfluidic Fabry-Perot (FP) refractive index (RI) sensors. The sensors are then coated with polydimethylsiloxane ...
Chemical Sensing Using Fiber Cavity Ring-Down Spectroscopy
Waveguide-based cavity ring-down spectroscopy (CRD) can be used for quantitative measurements of chemical concentrations in small amounts of liquid, in gases or in films. The change in ring-down time can be correlated to ...
