- Abstract: We propose two-mode two-photon microlaser using a single semiconductor
quantum dot grown inside a two-mode microcavity. We explore both incoherent and
coherent pumping at low temperatures to achieve suitable conditions for
two-mode two-photon lasing. The two-mode two-photon stimulated emission is
strongly suppressed but the single-photon stimulated emission is enhanced by
exciton-phonon interactions. In coherently pumped quantum dot one can achieve
large two-mode two-photon lasing where single-photon lasing is almost absent.
We also discuss generation of steady state two-mode entangled state using
two-photon resonant pumping.

We identify few-photon scattering mechanisms that lead to a full inversion of the emitter while transferring off-resonant photons from one mode to another.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

We investigated the fluorescence signals from Rhodamine 6G and LDS798 excited with a CW laser or an entangled photon pair source at 1060 nm.
We observed a signal that originates from hot-band absorption (HBA), which is one-photon absorption from thermally-populated vibrational levels of the ground electronic state.
For the typical conditions under which E2PEF measurements are performed, contributions from the HBA process could lead to a several orders-of-magnitude overestimate of the quantum advantage for excitation efficiency.
