Time-bin entanglement at telecom wavelengths from a hybrid photonic integrated circuit
Hannah Thiel, Lennart Jehle, Robert J. Chapman +9
Mass-deployable implementations for quantum communication require compact, reliable, and low-cost hardware solutions for photon generation, control and analysis. We present a fiber…
Understanding photoluminescence in semiconductor Bragg-reflection waveguides: Towards an integrated, GHz-rate telecom photon pair source
Silke Auchter, Alexander Schlager, Hannah Thiel +7
Compared to traditional nonlinear optical crystals, like BaBO, KTiOPO or LiNbO, semiconductor integrated sources of photon pairs may operate at pump wavelengths muc…
Observation of intensity squeezing in resonance fluorescence from a solid-state device
Hui Wang, Jian Qin, Si Chen +10
Intensity squeezing, i.e., photon number fluctuations below the shot noise limit, is a fundamental aspect of quantum optics and has wide applications in quantum metrology. It was p…
Quantum interference between light sources separated by 150 million kilometers
Yu-Hao Deng, Hui Wang, Xing Ding +18
We report an experiment to test quantum interference, entanglement and nonlocality using two dissimilar photon sources, the Sun and a semiconductor quantum dot on the Earth, which…
Temporally versatile polarization entanglement from Bragg-reflection waveguides
A. Schlager, B. Pressl, K. Laiho +5
Bragg-reflection waveguides emitting broadband parametric down-conversion (PDC) have been proven to be well suited for the on-chip generation of polarization entanglement in a stra…
Uncovering dispersion properties in semiconductor waveguides to study photon-pair generation
K. Laiho, B. Pressl, A. Schlager +5
We investigate the dispersion properties of ridge Bragg-reflection waveguides to deduce their phasematching characteristics. These are crucial for exploiting them as sources of par…
