Query: Generation of a two-photon state from a quantum dot in a microcavity
  under incoherent and coherent continuous excitation   We analyze the impact of both an incoherent and a coherent continuous
excitation on our proposal to generate a two-photon state from a quantum dot in
a microcavity [New J. Phys. 13, 113014 (2011)]. A comparison between exact
numerical results and analytical formulas provides the conditions to
efficiently generate indistinguishable and simultaneous pairs of photons under
both types of excitation.
