Abstract
- Functionalization of optical waveguides with submicron coatings of zinc peroxide (ZnO <subscript>2</subscript> ) and silica (SiO <subscript>2</subscript> ) nanoparticles (NPs) is reported that enabled selective concentration of acetone vapors in the vicinity of the waveguide, boosting the sensitivity of a mid infrared (MIR) on-chip detector. Controlled thickness was achieved by introducing precise control of the substrate withdrawal speed to the layer-by-layer (LbL) deposition technique.
