As an alternative\r\nto the usual cascaded biexciton-exciton emission, direct two-photon emission from the biexciton can be used.\r\nWith a high-quality optical resonator tuned to half the biexciton energy, a large proportion of the photons\r\ncan be steered into the two-photon emission channel. In this case the degree of polarization entanglement is\r\ninherently insensitive to the exciton fine-structure splitting. In the present work we analyze the biexciton emission\r\nwith particular emphasis on the influence of coupling of the quantum-dot cavity system to its environment.\r\nEspecially for a high-quality cavity, the coupling to the surrounding semiconductormaterial can open up additional\r\nphonon-assisted decay channels. Our analysis demonstrates that with the cavity tuned to half the biexciton energy,\r\nthe potentially detrimental influence of the phonons on the polarization entanglement is strongly suppressed—high\r\ndegrees of entanglement can still be achieved. We further discuss spectral properties and statistics of the emitted\r\ntwin photons."}],"date_created":"2018-07-05T12:08:38Z","status":"public","user_id":"49428","department":[{"_id":"15"},{"_id":"230"},{"_id":"35"}],"title":"Polarization-entangled twin photons from two-photon quantum-dot emission","date_updated":"2022-01-06T06:59:16Z","publication":"Physical Review B","project":[{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - Subproject A3","_id":"60"}]}
