摘要
The operation principle of a light modulator based on the magnetic or electric field control of the frequency of excitons in a quantum well of an optical microcavity is proposed and theoretically justified. It is shown that the main advantage of the proposed scheme is a large depth of modulation of the radiation intensity. The use of ferromagnetic semiconductors for the formation of exciton states in the quantum well makes possible the creation of a light modulator operating at room temperature in relatively weak magnetic fields.
