Molecular beam epitaxy has led to quantum wells which confine electrons and holes in one direction and microcavities which confine photons in one direction. In this proposal, 2D and 3D confinement of electrons is studied by using a magnetic field of up to 14 Tesla to quantize the quantum-well energy levels in one or both of the directions perpendicular to the direction of growth of the semiconductor cavity. By applying no field, a field parallel to the layers, and a field perpendicular to the lasers it is proposed to compare carrier relaxation and microcavity lasing for quantum wells, quantum wires and quantum dots, respectively, using the same quantum well and microcavity. Although fundamentally conceived and oriented, this research is strategic for manufacturing of low- threshold microlasers for use in the information superhighway, optical data storage, large panel displays, etc.

分子束外延产生了将电子和空穴限制在一个方向上的量子阱以及将光子限制在一个方向上的微腔。 在该提案中，通过使用高达 14 特斯拉的磁场来量子化与半导体腔生长方向垂直的一个或两个方向上的量子阱能级，从而研究电子的 2D 和 3D 限制。 通过不施加场、平行于层的场和垂直于激光器的场，提出使用相同的量子阱和微腔来分别比较量子阱、量子线和量子点的载流子弛豫和微腔激光。 尽管从根本上构思和定位，这项研究对于制造用于信息高速公路、光学数据存储、大面板显示器等的低阈值微型激光器具有战略意义。
