Study on dynamic behavior of ring-cavity quantum-cascade lasers with group velocity dispersion
… research on QCLs shows that the instability and dynamic behaviors are more complicated than conventional semiconductor lasers due to interaction among various intracavity effects, such as material nonlinearities, unique gain and dispersions. Group velocity dispersion (GVD) plays an important role …

Lebesgue ▼-Measure and Riemann ▼-Integration
Throughout the study of dynamic equations on time-scales, one traditionally finds many theorems involving the ▲ case (i.e., ▲-derivatives, ▲-measure, ▲-integrability, etc.) with only a brief mention of the ▼case. This thesis is designed to give a greater understanding of ▼-measurability and Riemann …
