Enhancing entangled two-photon absorption of Nile Red via temperature-controlled SPDC
Aleksa Krstić, Tobias Bernd Gäbler, Nitish Jain +6
Entangled two-photon absorption can enable a linear scaling of fluorescence emission with the excitation power. In comparison to classical two-photon absorption with a quadratic sc…

A hybrid source of quantum light for generation of frequency tunable Fock states
Aleksa Krstić, Priyanshu Tiwari, Florian Höhe +4
We propose a scheme for quantum-light generation in a nonlinear cavity hybridized with a 2-level system and theoretically show that, when excited by a series of controlled pump pul…

Non-perturbative theory of spontaneous parametric down-conversion in open and dispersive optical systems
Aleksa Krstić, Frank Setzpfandt, Sina Saravi
We develop a non-perturbative formulation based on the Green-function quantization method, that can describe spontaneous parametric down-conversion in the high-gain regime in nonli…
