Design optimization of optically pumped terahertz lasers in stepped quantum wells
Asymmetric stepped quantum wells (QWs) have been used in many optoelectronic devices. This paper proposes a modulation doping position at the edge of the stepped well to minimize the potential distortion caused by the doping. As a result, parasitic potential wells are eliminated, and the sensitivity...
