Spontaneous emission control in the solid-state: application to quantum optics

In this lecture, we will see that the spontaneous emission of a light emitter can be tailored to large extent by inserting it into a controlled electromagnetic environment. Such ideas were initially proposed and demonstrated thirty years ago in atomic physic. Thanks to the tremendous progress in semiconductor growth and processing, it is now possible to exploit these concepts in the solid-state, opening appealing perspectives for the realization of a novel generation of optoelectronic devices. Indeed, semiconductor quantum dots constitute nearly ideal artificial atoms (at least at cryogenic temperature). Using proper clean room processing, they can be integrated into various photonic structures. We will focus here on optical micro-cavities and some specific high-index waveguides, and show their interest for the realization of ultra-bright sources of quantum light.
