Double-armed cone-shaped flexoelectric transducer

open access: yesFrontiers in Physics, 2023
Compared with a single energy harvester, this tuning fork double-armed cone-shaped flexure transducer can fundamentally solve the problems of high resonance frequency, low output efficiency, and narrow bandwidth of the flexure transducer.

Cascaded forward Brillouin scattering to all Stokes orders

open access: yesNew Journal of Physics, 2017
Inelastic scattering processes such as Brillouin scattering can often function in cascaded regimes and this is likely to occur in certain integrated opto-acoustic devices.

Free-carrier-induced soliton fission unveiled by in situ measurements in nanophotonic waveguides

open access: yesNature Communications, 2016
Solitons are nonlinear waves that exist in diverse forms of matter. Here, Husko et al. use near-field measurements to observe the spatio-temporal evolution of optical pulses in a nanophotonic semiconductor waveguide, demonstrating that nonlinear photo ...

Nanometric holograms based on a topological insulator material

open access: yesNature Communications, 2017
Holograms generally need to be as thick as a wavelength of light to introduce the necessary optical phase shifts that create true three-dimensional images. Here, Yueet al.

Clustering the potential bandwidth upgrade of FTTH broadband subscribers

open access: yesIlkom Jurnal Ilmiah, 2021
A company needs to consider determining the customers’ potential before deciding to upgrade their bandwidth. It is important because, previously, determination was conducted randomly.

Phase-locking in cascaded stimulated Brillouin scattering

open access: yesNew Journal of Physics, 2016
Cascaded stimulated Brillouin scattering is a complex nonlinear optical process that results in the generation of several optical waves that are frequency shifted by an acoustic resonance frequency.
