Mid-Infrared opto-nanofluidic slot-waveguide for label-free on-chip chemical sensing Conference Paper uri icon


  • A mid-infrared sensor for label-free on-chip chemical detection was developed using an engineered nanofluidic channel consisting of a Si-liquid-Si slot-structure. A sensitivity with 75 times improvement was achieved compared to conventional evanescent-wave sensing.
