Surface plasmons excited by light in metal structures provide a means for manipulating
optical energy at the nanoscale. Plasmons are associated with the collective oscillations of …

The ongoing quest for ultra-compact optical devices has reached a bottleneck due to the
diffraction limit in conventional photonics. New approaches that provide subwavelength …

Electro-optic modulators are an indispensable part of photonic communication systems,
largely dictating the achievable transmission rate. Recent advances in materials and …

We propose several planar layouts of ultra-compact plasmonic modulators that utilize
alternative plasmonic materials such as transparent conducting oxides and titanium nitride …

Optical and electrical properties of indium tin oxide (ITO) films on Si substrates in the
thickness range from 10 nm to 100 nm were investigated. Spectroscopic ellipsometry was …

We report perfect light absorption due to the excitation of bound and radiative p-polarized
optical modes in epsilon-near-zero (ENZ) conducting oxide nanolayers with thicknesses as …

We present a promising application of epsilon-near-zero (ENZ) materials in optical
modulators. When a thin ENZ film is sandwiched in a single-mode waveguide, an ENZ-slot …

Ultra-thin films with low surface roughness that support surface plasmon-polaritons in the
infra-red and visible ranges are needed in order to improve the performance of devices …

The balance between extinction ratio (ER) and insertion loss (IL) dictates strict trade-off
when designing travelling-wave electro-optic modulators. This in turn entails significant …

We report on high-speed plasmonic-organic hybrid Mach-Zehnder modulators comprising
ultra-compact phase shifters with lengths as small as 19 µm. Choosing an optimum phase …
