A new review recounts the discovery of holographic interferometry, discusses its development, and itemizes some of its major applications.

A semiconducting structure absorbs mechanical energy provided by ultrasound excitation, with the erbium oxide providing a light emission.

A first step towards a new class of versatile nano-optical neural implants for brain research.

A new device could offer a higher sensitivity than today’s COVID-19 rapid antigen tests while also being faster and more cost-effective than PCR tests.

The main advantage of this new optical technology over PCR lies in the speed of sample processing.

Researchers from the University of Warsaw demonstrated how quantum information processing can efficiently provide information on matter hidden in light.

A simple but powerful approach uses very sensitive photon pairs and holds promise for applications that can achieve high measurement precisions.
