Towards third-order parametric down-conversion in optical fibers
Andrea Cavanna, Jonas Hammer, Cameron Okoth +8
Optical fibers have been considered an optimal platform for third-order parametric down-conversion since they can potentially overcome the weak third-order nonlinearity by their lo…
Idealised EPR states from non-phase matched parametric down conversion
C. Okoth, E. Kovlakov, F. Boensel +4
Entanglement of high dimensional states is becoming increasingly important for quantum communication and computing. The most common source of entangled photons is spontaneous param…
Microscale generation of entangled photons without momentum conservation
C. Okoth, A Cavanna, T. Santiago-Cruz +1
We report, for the first time, the generation of entangled photon pairs via type-0 spontaneous parametric down conversion in an ultra-thin wafer of lithium niobate in which momentu…
Seeded and unseeded high order parametric down conversion
Cameron Okoth, Andrea Cavanna, Nicolas Joly +1
Spontaneous parametric down conversion (SPDC) has been one of the foremost tools in quantum optics for over five decades. Over that time it has been used to demonstrate some of the…
