THz Superradiance from a GaAs: ErAs Quantum Dot Array at Room Temperature

THz Superradiance from a GaAs: ErAs Quantum Dot Array at Room Temperature

We report that an ErAs quantum-dot array in a GaAs matrix under 1550 nm pulsed excitation produces cooperative spontaneous emission—Dicke superradiance—in the terahertz frequency region at room temperature. Two key points pertain to the experimental evidence: (i) the pulsed THz emission power is muc...
