High-Lying Confined Subbands in Terahertz Quantum Cascade Lasers
In designing the terahertz quantum cascade lasers, electron injection manner indeed plays a significant role to achieve the population inversion. The resonant tunneling process is commonly employed for this injection process but waste more than 50% fraction of populations out of the active region ow...
