Abstract—
It is been established that thin semiconductor quantum rings in an external magnetic field have unique selection properties: by choosing the type of heterostructure and the geometry of the ring, it is possible to reduce its the energy spectrum to a single one-electron state with a predetermined binding energy and orbital and spin moments. In an external magnetic field, this binding energy can be discretely changed by varying the field value. The idea of creating an economical discretely tunable frequency laser based on thin semiconductor quantum rings as active elements is discussed.
