Bleaching the blur

Together with the groups of Prof. Dr. Rupert Huber (Regensburg), Prof. Dr. Miriam S. Vitiello (Pisa) and Prof. Dr. Edmund Linfield (Leeds) we developed a new concept for saturable absorbers in the terahertz spectral domain based on ultrastrong coupling of intersubband transitions to the resonant terahertz mode of a microresonator. These new devices could enable passive mode locking of future quantum cascade lasers.

The results have been published in Nature Communications.
