Resonant waveguide gratings (RWGs), also known as guided mode resonant (GMR)
gratings or waveguide‐mode resonant gratings, are dielectric structures where these …

Metasurfaces are ushering in an era of multifunctional control over optical wavefronts
realized with ultrathin planarized devices. Recent advances have been enabling …

Spatial transforms are a popular technique for designing periodic structures that are
macroscopically inhomogeneous. The structures are often required to be anisotropic …

We review principles and applications of nanophotonic devices based on electromagnetic
resonance effects in thin periodic films. We discuss the fundamental resonance dynamics …

A liquid crystal (LC) device, called a “q-plate”(QP), which is based on axially symmetric
photo-alignment was investigated. The electrically tunable LC QP device could be …

We demonstrated Graded Cavity Resonator Integrated Grating Filters (G-CRIGFs) that are
narrowband spectral reflectors, spectrally tunable over more than 40 nm around 850 nm …

We designed, fabricated, and tested, polarization selective, graded-reflectivity resonant
filters; based on a radial-gradient spatially-distributed, guided-mode resonance device …

We present a method for fabricating high aspect ratio metal-oxide, sub-wavelength grating
structures. These “nano-hair” structures are composed of alumina cylindrical pillars, partially …

New and novel sensing schemes require optical functions with unconventional spatial light
distributions, as well as complex spectral functionality. Micro-optical elements have shown …
