Resonant thermoelectric nanophotonics [PDF]

open access: yesNature 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.

Broadband highly directive 3D nanophotonic lenses

open access: yesNature Communications, 2018
While nanoscale emitters hold promise in single-photon devices, the directivity of their emission must be improved for practical applications. Here, Johlin et al.

Nonlinear cavity optomechanics with nanomechanical thermal fluctuations

open access: yesNature Communications, 2017
Optomechanical experiments often assume linear coupling between optical fluctuations and mechanical displacements. Here, Leijssenet al. experimentally demonstrate the nonlinear interaction from thermally induced fluctuations in a sliced nanobeam cavity ...

Large period spiking andburstingin anexcitable system with memory [PDF]

open access: yesEPJ 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

open access: yesScientific 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

Zinc Oxide Nanophotonics

open access: yesNanophotonics, 2015
The emerging field of nanophotonics initiated a dedicated study of single photon sources and optical resonators in new class of materials. One such material is zinc oxide (ZnO) that has been long considered only for classical light-emitting

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

open access: yesNature 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

Full-spectrum nonmetallic plasmonic carriers for efficient isopropanol dehydration

open access: yesNature Communications, 2022
A nonmetallic plasmonic heterostructure of W18O49 nanowires on reduced-graphene oxide is reported for the efficient dehydration of isopropanol to 100% propylene. The energy barrier is found to be reduced under full-spectrum irradiation.
