Modulation transfer function (MTF) quantifies an imaging system’s capacity to reproduce contrast at differing spatial frequencies and serves as a cornerstone metric for spatial resolution and image ...

A silver silicon nanodisk antenna performs all-optical modulation in 37 femtoseconds, bypassing the electron-phonon bottleneck that limits plasmonic devices. (Nanowerk News) Researchers at Xiamen ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Engineered Ag–Si interfacial plasmonic modes enable deconvolution-verified sub-100 fs all-optical modulation, overcoming the temporal bottleneck imposed by electron–phonon relaxation in conventional ...
