Magnetically controlled vertically emitting laser with anisotropic pumping

Abstract

A vertically emitting Faraday laser that is pumped by quantum wires or strongly anisotropic quan tum dots is considered. As distinct from a similar laser on a quantum well or isotropic quantum dots, such a laser is extremely sensitive to external magnetic field (up to switching off by magnetic field). This circum stance can be used for development of a rapidly tunable source of coherent radiation.
