Microresonator-enhanced, Waveguide-coupled Emission from Silicon Defect Centers for Superconducting Optoelectronic Networks [PDF]

arXiv, 2019
Superconducting optoelectronic networks could achieve scales unmatched in hardware-based neuromorphic computing. After summarizing recent progress in this area, we report new results in cryogenic silicon photonic light sources, components central to these architectures.

3D Nano‐architected Polymer Shell Enables Reconfigurable Stabilized Blue Phase Soft Crystals

Advanced Functional Materials, EarlyView.
Spherical polymer shells featuring nanostructure of blue phase (BP) disclinations form via in situ photo‐polymerization within BP liquid crystals, providing controlled anchoring for BP nucleation and growth at room temperature and beyond. This architected confinement enhances BP thermal stability over a broad temperature range while enabling dynamic ...

Ultra-compact and broadband tunable mid-infrared multimode interference splitter based on graphene plasmonic waveguide

, 2015
We propose and design an ultra-compact and broadband tunable multimode interference (MMI) splitter in mid-infrared based on graphene plasmonic waveguides. The size of the device is only 0.56{\mu}m*1.2{\mu}m, which corresponds to device area of only about

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

Advanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

Impedance matching in photonic crystal microcavities for Second Harmonic Generation

, 2005
By numerically integrating the three-dimensional Maxwell equations in the time domain with reference to a dispersive quadratically nonlinear material, we study second harmonic generation in planar photonic crystal microresonators.

Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

Advanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

Electrically Reconfigurable Intelligent Optoelectronics in 2-D van der Waals Materials [PDF]

arXiv
In optoelectronics, achieving electrical reconfigurability is crucial as it enables the encoding, decoding, manipulating, and processing of information carried by light. In recent years, two-dimensional van der Waals (2-D vdW) materials have emerged as promising platforms for realizing reconfigurable optoelectronic devices.

30 GHz optoelectronic mixing in CVD graphene [PDF]

arXiv, 2015
We report an optoelectronic mixer based on chemical vapour-deposited graphene. Our device consists in a coplanar waveguide that integrates a graphene channel, passivated with an atomic layer-deposited Al2O3 film. With this new structure, 30 GHz optoelectronic mixing in commercially-available graphene is demonstrated for the first time.
