Generation of a two-photon state from a quantum dot in a microcavity
Generation of a two-photon state from a quantum dot in a microcavity
We propose and characterize a two-photon emitter in a highly polarised, monochromatic and directional beam, realized by means of a quantum dot embedded in a linearly polarized cavity. In our scheme, the cavity frequency is tuned to half the frequency of the biexciton (two excitons with opposite spins) and largely …
