Quantum cascade lasers (QCLs) employ the midand far-infrared intersubband radiative transitions available in semiconducting heterostructures. Through the precise design and construction of these heterostructures the laser characteristics and output frequencies can be controlled. When fabricated, QCLs offer a lightweight and portable alternative to(More)
1 1 Evaluation configuration, image list and evaluation results are stored in a relational database, using either SQLite3 [3] for smaller data sets, or PostgreSQL [4] for operational data sets. In order to minimize size and maximize creation speed of the Image Pair Registration Record (IPRR) database, the database is divided into several tables, linked(More)
We present simulation results for two resonant phonon terahertz quantum cascade lasers using a self-consistent energy balance model, which determines the electron temperature for each conduction subband. These temperatures, along with the electron populations and scattering rates, are determined in a manner similar to previously published models. However,(More)
