Single Stack Active Region Nonlinear Quantum Cascade Lasers for Improved THz Emission

We present a single stack active region design for terahertz emission by difference frequency generation in quantum cascade lasers. The active region contains a single design, which is based on multiple optical transitions within one period. This results in both a giant nonlinearity and an ultra-bro...
