Using a time lens, Columbia Engineers resolve single photons 70 times faster than other techniques.

Experiments show short reaction time within 545 to 576 nanoseconds.

Australian researchers have developed a device that can generate electricity from thermal radiation based on similar technology to night-vision goggles.

An electron beam was steered through the optical near field of a photonic circuit, to allow the electrons to interact with the enhanced light.

Improved spectroscopy with an optical comb can detect different gases in the atmosphere simultaneously with ranged-resolved spectra.

Due to a Schottky barrier-tuning effect and trap-filling effect, hot-electron photocurrent in a gold electrode could be amplified tens of times.

Elfys is tapping into a growing demand for photodetectors with people increasingly wanting to measure their health and wellbeing. Today’s announced €3M round is dedicated...
