Fabrication of low-loss III-V Bragg-reflection waveguides for parametric down-conversion
Hannah Thiel, Marita Wagner, Bianca Nardi +8
Entangled photon pairs are an important resource for quantum cryptography schemes that go beyond point-to-point communication. Semiconductor Bragg-reflection waveguides are a promi…
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…
