Light emitters for quantum circuits.
The promise of a quantum internet depends on harnessing light to transmit information over fiber optic networks. Researchers in Sweden have developed integrated chips emit single photons on demand without the need for low temperatures.
The work is published in the journal Advanced Quantum Technologies: https://onlinelibrary.wiley.com/doi/10.1002/qute.202100032

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…
Improving optical fiberss.
Distortions in the signals passed through optical fibers are a massive challenge for modern communications infrastructure. University of Rochester researchers have devised a novel technique where pre-shaping the wave front and polarization of the optical signal reduces distortions during transmission.
The results can be viewed in Nature Communications: https://www.nature.com/articles/s41467-021-22071-w
