Second-order coherence properties of amplified spontaneous emission from a high-power tapered superluminescent diode
Jan Kiethe, Axel Heuer, Andreas Jechow
We study the degree of second-order coherence of the emission of a high-power multi-quantum well superluminescent diode with a lateral tapered amplifier section with and without fe…
The photon, its mode function and complementarity
Ralf Menzel, Robert Marx, Dirk Puhlmann +2
We probe the principle of complementarity by performing a double-slit experiment based on entangled photons created by spontaneous parametric down-conversion from a pump mode in a…
Entanglement, complementarity, and vacuum fields in spontaneous parametric down-conversion
Ralf Menzel, Axel Heuer, Peter W. Milonni
Using two crystals for spontaneous parametric down-conversion in a parallel setup, we observe two-photon interference with high visibility. The high visibility is consistent with c…
Frequency doubling of temporally incoherent light from a superluminescent diode in a periodically poled lithium niobate waveguide crystal
Henning Kurzke, Jan Kiethe, Axel Heuer +1
The amplified spontaneous emission from a superluminescent diode was frequency doubled in a periodically poled lithium niobate waveguide crystal. The temporally incoherent radiatio…
Complementarity in single photon interference - the role of mode functions and vacuum fields
R. Menzel, D. Puhlmann, A. Heuer
Single photon first order interferences of spatially separated regions from the cone structure of spontaneous parametric down conversion allow for analyzing the role of the mode fu…
Complementarity in Biphoton Generation with Stimulated or Induced Coherence
A. Heuer, R. Menzel, P. W. Milonni
Coherence can be induced or stimulated in parametric down-conversion using two or three crystals when, for example, the idler modes of the crystals are aligned. Previous experiment…
Phase Selective Quantum Eraser
A. Heuer, G. Pieplow, R. Menzel
A quantum-eraser experiment is reported with photon pairs generated by two synchronously pumped parametric down converters coupled via induced coherence. The complementarity betwee…
Transverse distinguishability of entangled photons with arbitrarily shaped spatial near- and far-field distributions
Robert Elsner, Dirk Puhlmann, Gregor Pieplow +2
Entangled photons generated by spontaneous parametric down conversion inside a nonlinear crystal exhibit a complex spatial photon count distribution. A quantitative description of…
Induced Coherence, Vacuum Fields, and Complementarity in Biphoton Generation
A. Heuer, R. Menzel, P. W. Milonni
We describe spontaneous parametric down-conversion experiments in which induced coherence across two coupled interferometers results in high-visibility single-photon interference.…
Phase memory across two single photon interferometers including wavelength conversion
Axel Heuer, Sebastian Raabe, Ralf Menzel
Detailed investigations of single photon 1st-order interferences of separated emitters allow for analyzing the role of the mode function in quantum optics. In an earlier Young's do…
Enhanced two-photon absorption using true thermal light
Andreas Jechow, Michael Seefeldt, Henning Kurzke +2
Two-photon excited fluorescence (TPEF) is a standard technique in modern microscopy but still affected by photo-damage of the probe. It was proposed that TPEF can be enhanced by us…
