Obiettivo del progetto (Objective)
'THz band remains the last region of electromagnetic spectrum which does not have wide application in modern technology due to lack of solid state source of THz radiation: compact, reliable and scalable. Fundamental objection preventing creation of such source is small rate of spontaneous emission of the THz photons: according to the Fermi Golden rule this rate is about tens of inverse milliseconds, while lifetime of the charge carrier in the solid typically lies in picoseconds range due to the efficient interaction with phonons. The rate of spontaneous emission of THz photons can be increased by application Purcell effect, but even in this case cryogenic temperature is required for the operation of solid state THz devices. Further increase of emission rate can be achieved via bosonic stimulation, when THz radiative transition occurs into the quantum state, in which condensate of bosons is formed. Such situation can be realized for transition between upper and lower polariton state in semiconductor microcavity in polariton lasing regime, in the case when parity excitonic parts of upper and lower polariton states is made different. In this case emission of THz radiation characterized by substantial quantum efficiency can be achieved even at room temperature. Further, pronounced non-linear properties of polaritonic systems lead to various non-linear effects in coupled system of polaritons and THz photons, what open the way for development of novel class of solid state devices, like compact THz short pulse generators, THz switch, and THz detectors.'
