Characterization of Gas Absorption Modules Based on Flexible Mid-Infrared Hollow Waveguides
A new gas absorption module, the substrate-embedded hollow waveguide (eHWG) model, is proposed. It consists of a substrate with a curved channel and a hollow waveguide. The hollow waveguide is curved into the channel and works as a gas absorption cell as well as a transmission medium for mid-infrare...
