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…
Experimental reconstruction of spatial Schmidt modes for a wide-field SU(1,1) interferometer
Gaetano Frascella, Roman V. Zakharov, Olga V. Tikhonova +1
We study the spatial mode content at the output of a wide-field SU(1,1) interferometer, i.e. a nonlinear interferometer comprising two coherently-pumped spatially-multimode optical…
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…
Detection-device-independent verification of nonclassical light
Martin Bohmann, Luo Qi, Werner Vogel +1
The efficient certification of nonclassical effects of light forms the basis for applications in optical quantum technologies. We derive general correlation conditions for the veri…
Properties of bright squeezed vacuum at increasing brightness
P. R. Sharapova, G. Frascella, M. Riabinin +6
Bright squeezed vacuum (BSV) is a non-classical macroscopic state of light, which can be generated through high-gain parametric down-conversion or four-wave mixing. Although BSV is…
Wide-field SU(1,1) interferometer
G. Frascella, E. E. Mikhailov, N. Takanashi +3
An interferometer uses a sequence of two optical parametric amplifiers for achieving sub-shot-noise sensitivity to a phase shift introduced in between. We present t…
