Award-winning cryogenic photolithography
The French group around Dr. Pascale Senellart at the LPN at CNRS has pioneered cryogenic in-situ optical lithography for manufacturing microcavities around single quantum dots. This allows for the deterministic production of electrically tunable and very bright single photon sources, with a yield increase by a factor of about 10.000 compared to previous approaches. For this remarkable achievement, she recently received the Médaille d’argent du CNRS 2014 (Silver Medal of Physics).
Based on her group’s work, attocube designed a three channel cryogenic confocal microscope, which has turned into a heavily used instrument in her laboratory. Many researchers in the world are currently benefiting from the photon sources produced by the system.
