Chalcogenide glass waveguides with paper-based fluidics for mid-infrared absorption spectroscopy
Abstract
We demonstrate the integration of paper fluidics with mid-infrared (MIR) chalcogenide waveguides to introduce liquid samples to the waveguide evanescent field for analysis. Spectroscopy of model analytes (water and isopropyl alcohol) having well-defined mid-IR absorptions, on a ZnSe rib waveguide fabricated on silicon, is demonstrated in the wavelength range of 2.6–3.7 μm, showing their O-H and C-H stretching absorptions. The results are compared with a theoretical waveguide model, achieving good agreement. It is concluded that the presence of paper in the evanescent field does not interfere with the waveguide measurements, opening up opportunities to combine low-cost paper-based fluidics and integrated photonic technologies.
