Resonance Fluorescence and Spontaneous Emission as Tests of QED
Do optical photons exist? Should we quantize the electromagnetic field in order to describe effects in the optical region? For more than twenty years these questions have been discussed in the domain of optical phenomena. Although QED provides a correct picture of all phenomena in the optical region, it has been argued that the photoelectric effect or the theory of spontaneous emission can be treated semiclassically and the quantum nature of the electromagnetic field is not necessary to describe these effects.
