A practical guide to loss measurements using the Fourier transform of the transmission spectrum
Hannah Thiel, Bianca Nardi, Alexander Schlager +2
Analyzing the internal loss characteristics and multimodedness of (integrated) optical devices can prove difficult. One technique to recover this information is to Fourier transfor…
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…
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…
Modally Resolved Fabry-Perot Experiment with Semiconductor Waveguides
B. Pressl, T. Günthner, K. Laiho +5
Based on the interaction between different spatial modes, semiconductor Bragg-reflection waveguides provide a highly functional platform for non-linear optics. Therefore, the contr…
Liquid-nitrogen cooled, free-running single-photon sensitive detector at telecommunication wavelengths
M. Covi, B. Pressl, T. Günthner +4
The measurement of light characteristics at the single- and few photon level plays a key role in many quantum optics applications. Often photodetection is preceded with the transmi…
