Phase-Matching-Free Sensing with Undetected Light Using a Nonlinear Thin-Film Metasurface
Toby Severs Millard, Nathan Gemmell, Ross C. Schofield +4
In this article, we report classical sensing with undetected light at a wavelength of 1500 nm, detected on a silicon camera at 580 nm, using four-wave mixing from a plasmonic metas…

Quantum undetected optical projection tomography
Nathan R. Gemmell, Emma Pearce, Jefferson Florez +3
Quantum imaging with undetected photons (QIUP) is an emerging technique that decouples the processes of illuminating an object and projecting its image. The properties of the illum…
