Author(s): Miguel Montes Bajo, Julen Tamayo-Arriola, Maxime Hugues, Jose M. Ulloa, Nolwenn Le Biavan, Romain Peretti, Francois H. Julien, Jerome Faist, Jean-Michel Chauveau, and Adrian Hierro Highly doped multiple quantum wells (MQWs) are significant for infrared optoelectronics, plasmonics, and the physics of strong light-matter coupling. The authors reveal a multisubband plasmon (MSP) that arises from the couplings among several intersubband transitions in (Mg,Zn)O/ZnO MQWs, due to the outstandingly dense two-dimensional electron gas. Here the MSP energy is up to three times that of the constituent intersubband transitions, illustrating the potential of this system for optoelectronic applications in the infrared, which could be extended to the terahertz range by appropriate quantum-well design.
