Hybrid light-matter states in low dimensional quantum materials with tailored functionalities
The broad objective of the proposed research is the study of optical and transport properties of mixed light-matter quasiparticles, polaritons, formed in low-dimensional semiconductor structures in the strong coupling regime. The ultimate goal is the design and realization of novel low-power optoelectronic coherent devices (polaritonic circuits) for optical information transmission and processing operating at room temperature. Because of their extremely low effective mass and strong inter- particle interactions, quantum collective phenomena can be observed in polariton systems at surprisingly high temperatures. Recent experimental discoveries of Bose-Einstein condensation and superfluidity of exciton-polaritons and achievement of polariton lasing at room temperature open a perspective of use of these coherent quantum phenomena in a new generation of opto- and micro-electronic devices.
