Resonant thermoelectric nanophotonics [PDF]

Nature Nanotechnology, 2017
Photodetectors are typically based either on photocurrent generation from electron-hole pairs in semiconductor structures or on bolometry for wavelengths that are below bandgap absorption. In both cases, resonant plasmonic and nanophotonic structures have been successfully used to enhance performance.

Large period spiking andburstingin anexcitable system with memory [PDF]

EPJ Web of Conferences, 2023
Excitability in dynamical systems refers to the ability to transition from a resting stationary state to a spiking state when a parameter is varied. It is the mechanism behind spike generation in neurons.

Impact of GST thickness on GST-loaded silicon waveguides for optimal optical switching

Scientific Reports, 2022
Phase-change integrated photonics has emerged as a new platform for developing photonic integrated circuits by integrating phase-change materials like GeSbTe (GST) onto the silicon photonics platform. The thickness of the GST patch that is usually placed

A framework for scintillation in nanophotonics

Science, 2022
Bombardment of materials by high-energy particles often leads to light emission in a process known as scintillation. Scintillation has widespread applications in medical imaging, x-ray nondestructive inspection, electron microscopy, and high-energy particle detectors. Most research focuses on finding materials with brighter, faster, and more controlled

Strong-coupling of WSe2 in ultra-compact plasmonic nanocavities at room temperature

Nature Communications, 2017
Two-dimensional materials offer the prospect of excitonic devices operating at room-temperature. Here, Kleemann et al. demonstrate that by tuning the number of WSe2 layers in a nanoparticle-on-mirror geometry, room-temperature plasmon strong-coupling can

Toward On-Chip Nascent All-van-der-Waals Polarization Optical Elements for Nanoscale Photonic Applications. [PDF]

Nanophotonics
Twisted ReSe2/α−MoO3 van der Waals heterostructures pave the way towards next‐generation polarization nanophotonic applications, where combining two biaxial layers—a triclinic source of linearly polarized emission and an orthorhombic polarization‐conversion slab—establishes a practical route for fully integrated on‐chip all‐van der Waals polarization ...
