Optical Wells for Super-Photons Could be Forerunner of Quantum Circuits
BONN, Germany, Aug. 24, 2017 — Experiments with a “super-photon,” also known as a Bose-Einstein condensate and formed when thousands of photons merge with each other, led scientists to create an optical well that could lead to a novel approach to variable microstructuring in photonics. In the experimental setup, a laser beam was bounced back and forth rapidly between two mirrors. Researchers placed a dye-polymer solution within an ultrahigh-finesse microcavity between the mirrors, which cooled the laser
