“…We use a data set of the emission from a planar semiconductor microcavity in the lasing regime using non-resonant optical pumping with 4 mW excitation power [12] as an example to visualize the technique. To calculate the intensity correlation function, one needs to know the number of photon pairs detected at times t and t τ + , respectively.…”

“…Figure 1 shows an exemplary choice of variables for the binning process of the 4-mW excitation power data set used in [12]. The binned data set is analyzed with an algorithm that counts all -not just consecutive -photon pairs inside the streaks and sorts them according to the time of detection of the first photon and the time delay τ .…”

Abstract:We present a detailed discussion of a recently demonstrated experimental technique capable of measuring the correlation function of a pulsed light source with picosecond time resolution. The measurement involves a streak camera in single photon counting mode, which is modified such that a signal at a fixed repetition rate, and well defined energy, can be monitored after each pulsed laser excitation. The technique provides further insight into the quantum optical properties of pulsed light emission from semiconductor nanostructures, and the dynamics inside a pulse, on the subnanosecond time scale. ©2010 Optical Society of America

“…Although more recent experiments could generate single photons with coherence times up to several microseconds [16][17][18] HBT setups are still used. Placing two detectors in the spatial mode of the photon flux, the beam splitter is not required any more, but still the photons are "split" to either of the detectors at different locations [19].Recently, measurements of photon statistics with single detection devices based on a gated Geiger mode InGaAs APD [20] or a modified streak camera in single-photon counting mode [21,22] were reported. Nonclassical dynamic features were observed in the light from semiconductor microlasers.…”

Measuring the quantum nature of light with a single source and a single detector

An elementary experiment in optics consists of a light source and a detector. Yet, if the source generates nonclassical correlations such an experiment is capable of unambiguously demonstrating the quantum nature of light. We realized such an experiment with a defect center in diamond and a superconducting detector. Previous experiments relied on more complex setups, such as the Hanbury Brown and Twiss configuration, where a beam splitter directs light to two photodetectors, creating the false impression that the beam splitter is a fundamentally required element. As an additional benefit, our results provide a simplification of the widely used photon-correlation techniques. Loudon [4] that a much simpler experiment in which the light is arranged to fall on a single phototube would be sufficient. Here, we perform such an experiment and show single-photon statistics from a quantum emitter with only one detector. The superconducting detector we fabricated has a dead time shorter than the coherence time of the emitter. No beam splitter is employed, yet anticorrelations are observed. Our work simplifies a widely used photon-correlation technique [5,6].A single-photon Fock state is a single excitation of a mode k of the electromagnetic field a † k |0 . A more general single-photon state appropriate to describe the final wave packet generated by a single-photon source in an experiment is a superposition of different spatio-temporal modes containing in total one excitation. The probability P (n) of finding exactly n excitations in the modes may distinguish different states of light. Figures 1(a) and 1(b) show a schematic representation of a coherent state where P (n) is a Poissonian distribution together with a number (or Fock) state with exactly 1 photon per mode, respectively. In the case of a single-photon state (n = 1) detection of a single excitation projects the measured mode to the vacuum state; i.e., the probability of detecting another photon in the very same mode is zero. Since the temporal mode profile is associated with a characteristic coherence time τ c , coincidence events within the time interval τ c are absent; antibunching is observed. On the contrary, * steudle@physik.hu-berlin.de † http://www.physik.hu-berlin.de/nano for a coherent state the probability of detecting a photon is independent of any previous detection event. Antibunching is thus not only a consequence of photons being indivisible particles but requires a specific quantum statistical distribution of discrete excitations. The latter requirement is overlooked in a simple explanation of antibunching in a HBT experiment [ Fig. 1(c)]. There a photon is regarded as a classical indivisible particle and necessarily has to decide which path to take when impinging on a beam splitter. Such an interpretation is certainly naïve. It even led to paradoxical conclusions, such as in some implementations of Wheeler's delayed choice paradox [7].Today, many different sources have been realized that generate antibunched light such as single-photon sources ...

We present a theoretical study of a quantum‐dot‐based microcavity laser where two nearly degenerate high‐Q modes are involved in the laser dynamics. To analyze the coupled carrier‐photon system we have extended a single mode microscopic semiconductor theory to the case of two modes and have also taken the crosscorrelation functions into account. Our theoretical results show that the mode which loses the mode competition exhibit super‐thermal photon bunching (gfalse(2false)false(0false)>2). This interesting feature is traced back to mode coupling induced by the gain medium.The strong correlation between the two modes is revealed by calculation of the photon cross correlation functions.
