In this paper, we report the experimental characterization of highly nonlinear GeSbS
chalcogenide glass waveguides. We used a single-beam characterization protocol that …

We propose an all-solid-state tunable Bragg filter with a phase transition material as the
defect layer. Bragg filters based on a vanadium dioxide defect layer sandwiched between …

Properties of reflection and transmission spectral filters based on Bragg gratings in
subwavelength grating (SWG) metamaterial waveguides on silicon-on-insulator platform …

Active wave manipulation by ultracompact meta-devices is highly embraced in recent years,
but a major concern still exists due to the lack of functional reconfigurability. Moreover, the …

Phase-change materials (PCMs) allow for non-volatile resonance tuning of nanophotonic
components. Upon switching, they offer a large dielectric contrast between their amorphous …

In this work, phase change chalcogenide Ge2Sb2Te5 (GST) thin films were fabricated by
magnetron sputtering. The optical properties, especially the optical constants (refractive …

We report on the realization of a high quality distributed Bragg reflector with both high and
low refractive index layers lattice matched to ZnTe. Our structure is grown by molecular …

Metamaterials composed of metallic antennae arrays are used as they possess
extraordinary optical transmission (EOT) in the terahertz (THz) region, whereby a giant …

Polaritons formed by the coupling of light and material excitations enable light-matter
interactions at the nanoscale beyond what is currently possible with conventional optics …

The retention-of-state functionality provided by memories is fundamental to any Turing
machine and neural network, hence is critical for any information system today. While …
