Heralded generation of high-purity ultrashort single photons in programmable temporal shapes
Vahid Ansari, Emanuele Roccia, Matteo Santandrea +9
We experimentally demonstrate a source of nearly pure single photons in arbitrary temporal shapes heralded from a parametric down-conversion (PDC) source at telecom wavelengths. Th…
Streak-camera measurements of single photons at telecom wavelength
Markus Allgaier, Vahid Ansari, Christof Eigner +8
Up to this point streak-cameras have been a powerful tool for temporal characterization of ultrafast light pulses even at the single photon level. However, the low signal-to-noise…
Fast time-domain measurements on telecom single photons
Markus Allgaier, Gesche Vigh, Vahid Ansari +5
Direct measurements on the temporal envelope of quantum light are a challenging task and not many examples are known since most classical pulse characterisation methods do not work…
A waveguide cavity resonator source of squeezing
M. Stefszky, R. Ricken, C. Eigner +3
We present the generation of continuous-wave optical squeezing from a titanium-indiffused lithium niobate waveguide resonator. We directly measure 2.9\pm 0.1 dB of single-mode sque…
