Emitters based on semiconductor Bragg microcavities.

This paper presents a brief review of the progress in the development of two types of semiconductor emitters based on semiconductor Bragg microcavities. The first type of these emitters is a vertical-cavity laser based on AlGaAs. The laser demonstrates stable single-mode lasing at a wavelength of 795 nm, which opens prospects for its use in miniature atomic frequency standards on the basis of Rb. The second type is a single-photon emitter based on semiconductor quantum dots. The design of such an emitter was developed on the basis of a semiconductor Bragg microcavity providing a high level of external quantum efficiency of the emitter (up to 80%) and high performance due to the Purcell effect.
