Abstract
The optical gain spectra of a single triple quantum well (TQW) mid-infrared (MIR) laser element suitable for incorporation in a quantum cascade configuration are investigated. The kinetics of the carrier transport in the TQW structure are provided using a four-level rate equation model. The low gain per element at MIR frequencies illustrates the need for several such elements. Preliminary gain calculations for a near-infrared (NIR) structure are also performed.
