WebAug 19, 2024 · By expanding the state vector in the Fock space { n a, n b, n c, n p }, , with n a,b,c = n for the photon-triplet generation, the amplitude and thus the state vector can be obtained numerically. Since we are only interested the photon triplets, the reduced state of the triplets can be obtained by tracing out the pump mode (figure 1). WebAt first glance, our rather low emission rate of photon triplets under the incoherent pulsed excitation regime might imply an inefficient generation of entangled photon triplets using QDMs. However, we predict a drastic improvement of the photon triplet counts under resonant excitation due to the profound suppression of background noise and ...

WebWe present an experimental proposal for the generation of photon triplets based on third-order spontaneous parametric downconversion in thin optical fibers. Our analysis includes expressions for the quantum state, which describes the photon triplets and for the generation rate in terms of all experimental parameters. We also present, for a specific … There are three basic mechanism for photon upconversion in inorganic materials and at least two distinct mechanisms in organic materials. In inorganic materials photon upconversion occurs through energy transfer upconversion (ETU), excited-state absorption (ESA) and photon avalanche (PA). Such processes can be observed in materials with very different sizes and structures, including optical fibers, bulk crystals or nanoparticles, as long as they contain any of the active i…
