title: Single-shot fabrication of waveguide ternary gratings with narrow-band optical response.
abstract: Single-shot fabrication of three sets of nano-scale grating structures with different periods is reported, which are constructed on a glass substrate coated with a waveguide layer made of 200-nm-thick indium tin oxide (ITO). Multiple waveguide resonance modes are observed in the visible spectral range with a bandwidth as narrow as 10 nm. Angle-resolved tuning properties of these resonance modes enable simultaneous three-color optical response of the nanodevice to cover the whole visible spectrum. This implies very simple methods for the potential design and realization of flexible optoelectronic devices.
