The purpose of this research is the development of semi-conductor coherent sources for lightwave applications. While the semi-conductor laser has achieved prevalence as a suitable source, new materials developments are occurring rapidly and are influencing such lasers. One such crystalline material is the so-called doping superlattice. This involves the generation of a periodic crystal lattice superimposed upon the underlying crystal lattice, the "superlattice" being obtained by preferential doping. This particular technique allows design of the coupling between the optical beam and the crystal as well as a certain degree of tunability of the frequency.

本研究的目的是开发用于光波应用的半导体相干源。虽然半导体激光器作为一种合适的光源已经普及，但新材料的开发正在迅速发生，并正在影响这类激光器。其中一种晶体材料就是所谓的掺杂超晶格。这涉及到叠加在底层晶格上的周期性晶格的产生，通过优先掺杂获得“超晶格”。这种特殊的技术允许设计光束和晶体之间的耦合以及一定程度的频率可调谐。
