Invited Article: Enhanced four-wave mixing in waveguides integrated with graphene oxide
APL Photonics, 2018 We demonstrate enhanced four-wave mixing (FWM) in doped silica waveguides integrated with graphene oxide (GO) layers. Owing to strong mode overlap between the integrated waveguides and GO films that have a high Kerr nonlinearity and low loss, the FWM ...

Small Methods, EarlyView.Resonant four‐wave mixing (FWM) microscopy reveals a spatial modulation of the third‐order nonlinear optical response in vanadium‐doped WS2 monolayers. This robust nonlinear contrast technique tracks the preferential accumulation of vanadium dopants along the structural bisection lines of the synthesized flakes.

Polarization Control Methods for Mitigating Four-Wave Mixing Effect in NG-EPON Networks
PhotonicsIn order to meet the growing traffic demands, the formulation of the NG-EPON protocol is under heated discussion. Therefore, for the wavelength allocation scheme of NG-EPON, adopting O-band wavelengths is considered as the potentially feasible solution ...

Gestational diabetes in multifetal versus singleton pregnancies: A multicenter cohort study
Acta Obstetricia et Gynecologica Scandinavica, EarlyView.Gestational diabetes in multifetal pregnancies was associated with increased maternal morbidity but less adverse neonatal and long‐term offspring outcomes than in singleton pregnancies, suggesting that current diagnostic thresholds derived from singleton gestations may not fully reflect the unique metabolic and clinical characteristics of multifetal ...

Enhanced nonlinearity of four-wave mixing via Rydberg–Rydberg interactions
New Journal of Physics, 2022 We investigate the four-wave mixing (FWM) nonlinearity in an ensemble of cold Rydberg atoms with each of them regarded as a double-ladder system. The interaction is studied from the view of generating a signal field in virtue of three applied lasers ...

Visual Cues for Logical Reasoning about Text Enhance Metacognitive Sensitivity
Computer Graphics Forum, EarlyView.Abstract An important part of critical thinking is analyzing the logical structure of inferences made in text, such as checking whether if–then rules appearing in legal regulations or scientific arguments are applied correctly. Metacognitive sensitivity, defined as feeling confident about one's correct answers and uncertain about incorrect ones, is an ...

Periodic fibre devices for advanced applications in all-optical systems
, 2012 The main objective of this work is to investigate advanced applications of fibre gratings with the combination of nonlinear fibre optical effects, including the stimulated Raman scattering (SRS), Kerr effects, four-wave mixing (FWM) and second-harmonic ...

Investigating Performance and Practices with Univariate Distribution Charts
Computer Graphics Forum, EarlyView.Abstract A range of charts with different strengths and weaknesses exists to support the visual analysis of univariate distributions, with a limited understanding of which charts best support which tasks and users, and how practitioners use charts. We categorize the available charts for univariate distributions into four groups and present the results ...
