Nonlinear cavity optomechanics with nanomechanical thermal fluctuations
Nature 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]
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.

Nanophotonic computational design
Optics Express, 2013 In contrast to designing nanophotonic devices by tuning a handful of device parameters, we have developed a computational method which utilizes the full parameter space to design linear nanophotonic devices. We show that our method may indeed be capable of designing any linear nanophotonic device by demonstrating designed structures which are fully ...

Silicon-on-insulator photonic crystal miniature devices with slow light enhanced third-order nonlinearities [PDF]
, 2012 The effects of the slow-down factor on third-order nonlinear effects in silicon-on-insulator photonic crystal channel waveguides were investigated. In the slow light regime, with a group index equal to 99, these nonlinear effects are enhanced but the ...

Towards all-dielectric metamaterials and nanophotonics [PDF]
, 2015 We review a new, rapidly developing field of all-dielectric nanophotonics which allows to control both magnetic and electric response of structured matter by engineering the Mie resonances in high-index dielectric nanoparticles.

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

Quantum-Coherence-Enhanced Surface Plasmon Amplification by Stimulated Emission of Radiation [PDF]
, 2013 We investigate surface plasmon amplification in a silver nanoparticle coupled to an externally driven three-level gain medium, and show that quantum coherence significantly enhances the generation of surface plasmons.
