Light meets superconductivity.
Researchers at Ecole Polytechnique Fédérale de Lausanne have developed a novel approach using light to read data from low temperature superconducting devices. Using light avoids the problems caused by heat transfer through conventional cables.
The work is published in the journal Nature Electronics: https://www.nature.com/articles/s41928-021-00570-4

Diagnosing prostate cancer with light.
Prostate cancer is the second most common cancer globally in men, but rapid and accurate screening remains a challenge. Researchers from Chernivtsi National University & University of Oulu demonstrate a diagnostic method using polarized light that can quickly analyze prostate tissue samples for signs of cancer.
The results are published in Scientific Reports: https://www.nature.com/articles/s41598-021-83986-4

The future of LED displays?
Small and efficient micro-LEDs are a promising technology for the next generation of displays. A new red light micro-LED developed at KAUST promises to boost the future of full-colour displays based on just a single semiconductor.
Details of their device can be found in Optics Letters: https://www.osapublishing.org/ol/fulltext.cfm?uri=ol-46-8-1912&id=450025

Investigation of InGaN-based red/green micro-light-emitting diodes
We investigated the performance of InGaN-based red/green micro-light-emitting diodes (µLEDs) ranging from 98×98µm2 to 17×17µm2. The average forward voltage at 10A/cm2 was independent of the dimension of µLEDs. Red µLEDs exhibited a larger blueshift of the…
Liquid light.
Researchers at St. Petersburg State University have experimentally observed the formation of a Bose-Einstein condensate in molybdenum diselenide. The condensate contains thousands of exciton polaritons, or ‘liquid light’ quanta, which can be used to carry information in quantum computing applications.
The work has recently been published in Nature Materials: https://www.nature.com/articles/s41563-021-01000-8

Understanding biology with light.
A team at Aston University has shown how light can be used to assess structures and changes in biological tissues. By looking at changes in the polarisation of light passing through the tissues, maps can be produced that correlate with the tissue structures.
