Abstract

Abstract The g(2) correlation function of a light beam depends on its photon statistcs. In quantum optics, this effect can be used to determine the effective mode number of a type II parametric downconversion source. However, the outcome is very sensitive against background light from other sources. We consider the experimental challenges of this approach and introduce a simple model to account for influence of the background. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Parametric oscillation in semiconductor microcavities: nonlinear and quantum effects

Jean‐Philippe Karr, A. Baas, Marco Romanelli +2 more

Abstract We report the observation of optical bistability in a semiconductor microcavity pumped at the “magic angle” above the parametric oscillation threshold. Experimental evidence is given in the form of a hysteresis cycle of the nonlinear emission as a function of the pump intensity. A model analogous to those developped for triply resonant Optical Parametric Oscillators (OPO) is in good agreement with the experimental findings. In the second part, we study the potential application of the parametric oscillation regime to quantum optics. The quantum correlations between the emitted “signal” and “idler” beams are computed. We show that very strong quantum correlations between the signal and idler polaritons can be achieved. However the quantum effects in the outgoing light fields are strongly reduced due to the large mismatch in the coupling of the signal and idler polaritons to the external photons.

Effective second-order correlation function and single-photon detection

P. Grünwald

Abstract Quantum-optical research on semiconductor single-photon sources puts special emphasis on the measurement of the second-order correlation function g (2) ( τ ), arguing that g (2) (0) < 1/2 implies the source field represents a good single-photon light source. We analyze the gain of information from g (2) (0) with respect to single photons. Any quantum state, for which the second-order correlation function falls below 1/2, has a nonzero projection on the single-photon Fock state. The amplitude p of this projection is arbitrary, independent of g (2) (0). However, one can extract a lower bound on the single-to-multi-photon-projection ratio. A vacuum contribution in the quantum state of light artificially increases the value of g (2) (0), cloaking actual single-photon projection. Thus, we propose an effective second-order correlation function g ˜ ( 2 ) ( 0 ) , which takes the influence of vacuum into account and also yields lower and upper bounds on p . We consider the single-photon purity as a standard figure of merit in experiments, reinterpret it within our results and provide an effective version of that physical quantity. Besides comparing different experimental and theoretical results, we also provide a possible measurement scheme for determining g ˜ ( 2 ) ( 0 ) .

Photon statistics in parametric down-conversion process

Nilakantha Meher, Anand K. Jha

Using the zero time-delay second-order correlation function, we investigate how the photon statistics of the field-modes generated by parametric down-conversion (PDC) process depends on photon statistics of the pump field-mode.

Telecom single‐photon source with horn structure

K. Takemoto, Shinichi Hirose, Motomu Takatsu +5 more

Abstract Nearly background free 1.5‐μm single‐photon source has been demonstrated using quasiresonant pulsed excitation. We performed a micro‐photoluminescence excitation together with photon‐correlation experiments, and then we compared photon statistics in nonresonant and quasiresonant excitation case. When we tuned the pump laser to the quasiresonant state which is 18.6 meV higher than the ground state excitonic transmission, almost background‐free luminescence was found at 1524.3 nm. The second‐order correlation function at time delay of zero, g(2)(0), was reduced to 0.017 when we carefully estimated noise contributions of after‐pulses and dark counts in InGaAs APD detectors. This result opens up the possibility of promoting high quality single‐photon source at telecommunication wavelength. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Simple and practical method of characterizing the parametric down-conversion source

Dong Wang, Juan Wu, Liang-Yuan Zhao +5 more

Parametric down-conversion (PDC) sources play an important role in quantum information processing, therefore characterizing their properties is necessary. Here we present a statistical model to assess the properties of the PDC source with certain distribution, such as the brightness and photon channel transmissions, we only need to measure the singles and coincidences counts in a few seconds. Furthermore, we validate the model by applying it to a PDC source generating highly non-degenerate photon pairs. The results of the experiment indicate that our method is more simple, efficient, and less time consuming.

Fluctuations and dark count rates in superconducting NbN single‐photon detectors

Andreas Engel, Alexei D. Semenov, Heinz‐Wilhelm Hübers +2 more

We measured the temperature- and current-dependence of dark count rates of a superconducting singlephoton detector. The detector's key element is a 84 nm wide meander strip line fabricated from a 5 nm thick NbN film. Due to its reduced dimensions various types of fluctuations can cause temporal and localized transitions into a resistive state leading to dark count events. Adopting a recent refinement of the hotspot model we achieve a satisfying description of the experimental dark count rates taking into account fluctuations of the Cooper-pair density and current-assisted unbinding of vortex-antivortex pairs.
