Strathclyde Chancellor's Fellow

Institute of Photonics

Personal statement

Dr. Johannes Herrnsdorf is a research associate at the Institute of Photonics. His main interests are the exploration of the physics of gallium nitride micro-LEDs and their development towards a wide range of applications including communications and imaging.

His research has equipped him with a broad background in semiconductor-based photonics, including solution processible organic and inorganic materials for colour conversion and lasers, and semiconductor devices for operation from the ultra-violet through to the near infrared wavelengths. He currently focusses on structured digital illumination, which is scalable from microscopic through to kilometre ranges, and on the few-photon operation of LED-enabled optical links. Dr Herrnsdorf has been awarded an EPSRC UKRI Innovation Fellowship to support his work on structured illumination and digital lighting at the few-photon level.
