Subwavelength-Grating Metamaterial Structures for Silicon Photonic Devices
Proceedings of the IEEE, 2018 Segmenting silicon waveguides at the subwavelength scale produce an equivalent homogenous material. The geometry of the waveguide segments provides precise control over modal confinement, effective index, dispersion and birefringence, thereby opening up ...

The Focusing Property of Immersed Plasmonic Nanolenses Under Radially Polarized Illumination
IEEE Photonics Journal, 2013 The focusing property of immersed plasmonic nanolenses was theoretically studied by a rigorous electromagnetic numerical analysis method. The immersed plasmonic nanolens consists of a through central hole surrounded by a set of concentric slits with a ...

Guided-Mode Resonances in GaN Membrane Grating
IEEE Photonics Journal, 2014 This paper proposes guided-mode resonant GaN grating that are implemented on a GaN-on-silicon wafer structure. Numerical simulations based on rigorous coupled wave analysis (RCWA) are performed to model multiple resonances in thick GaN membranes.

Influence of Subwavelength Grating Asymmetry on Long-Wavelength Infrared Transmittance Filters
IEEE Photonics Journal, 2018 Subwavelength dielectric gratings provide a means of narrowband spectral filtering by coupling to quasi-guided leaky modes, providing a high reflectivity background and narrowband transmittance via Fano resonance behavior.

Interplay between evanescence and disorder in deep subwavelength photonic structures
Nature Communications, 2016 Deep subwavelength features are expected to have minimal impact on wave transport. Here we show that in contrast to this common understanding, disorder can have a dramatic effect in a one-dimensional disordered optical system with spatial features a ...
