Flow cell for mode-specific, integrated optical waveguide spectroscopy in aqueous superstrates
In this communication, we describe the design, construction, and operation of a flow cell that allows for proper waveguide coupling in liquid media. Preliminary results showing mode-dependent attenuation of evanescent energy by surface-bound molecules are presented which demonstrate the feasibility of mode-specific IOW spectroscopy at the solid/liquid interface.
