On the basis of density matrix formalism a mathematical model describing lasing in quantum well semiconductor nanostructures is developed. In its frame, an inversionless room-temperature operating amplifier or laser widely tunable in the far-infrared and terahertz (THz) region is suggested. Its working frequency can be varied by several times via the simple… (More)
