Extraordinary evanescent field confinement waveguide sensor for mid-infrared trace gas spectroscopy
Nanophotonic waveguides are at the core of a great variety of optical sensors. These structures confine light along defined paths on photonic chips and provide light–matter interaction via an evanescent field. However, waveguides still lag behind free-space optics for sensitivity-critical applicatio...
