Terahertz quantum cascade lasers operating up to ~ 200 K with optimized oscillator strength and improved injection tunneling

Terahertz quantum cascade lasers operating up to ~ 200 K with optimized oscillator strength and improved injection tunneling

A new temperature performance record of 199.5 K for terahertz quantum cascade lasers is achieved by optimizing the lasing transition oscillator strength of the resonant phonon based three-well design. The optimum oscillator strength of 0.58 was found to be larger than that of the previous record (0....
