Photonic signal processing on electronic scales: electro-optical field-effect nanoplasmonic modulator.
TLDR
A highly efficient approach for the modulation of photonic signals at the nanoscale is developed, combining an ultrasubwavelength plasmonic guiding scheme with a robust electroabsorption effect in degenerate semiconductors.Abstract:
We develop a highly efficient approach for the modulation of photonic signals at the nanoscale, combining an ultrasubwavelength plasmonic guiding scheme with a robust electroabsorption effect in degenerate semiconductors. We numerically demonstrate an active electro-optical field-effect nanoplasmonic modulator with a revolutionary size of just 25 × 30 × 100 nm(3), providing signal extinction ratios as high as 2 at switching voltages of only 1 V. The design is compatible with complementary metal-oxide-semiconductor (CMOS) technology and allows low-loss insertion in standard plasmonic and Si-photonic circuitry.read more

Electro-optical modulation of a silicon waveguide with an “epsilon-near-zero” material
TL;DR: This modulator leverages the combination of a local electric field enhancement and increased absorption in the ITO when this material is locally brought into an ENZ state via electrical gating, which leads to large changes in modal absorption upon gating.

Circuits with Light at Nanoscales: Optical Nanocircuits Inspired by Metamaterials
TL;DR: It is shown that the concept of metamaterial-inspired nanoelectronics (“metactronics”) can bring the tools and mathematical machinery of the circuit theory into optics, may link the fields of optics, electronics, plasmonics, and meetamaterials, and may provide road maps to future innovations in nanoscale optical devices, components, and more intricate nanoscales metammaterials.
