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…
Optimizing the spectro-temporal properties of photon pairs from Bragg-reflection waveguides
H. Chen, K. Laiho, B. Pressl +6
Bragg-reflection waveguides (BRWs) fabricated from AlGaAs provide an interesting non-linear optical platform for photon-pair generation via parametric down-conversion (PDC). In con…
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…
Direct measurement of second-order coupling in a waveguide lattice
Robert Keil, Benedikt Pressl, René Heilmann +3
We measure the next-nearest-neighbour coupling in an array of coupled optical waveguides directly via an integrated eigenmode interferometer. In contrast to light propagation exper…
Obtaining tight bounds on higher-order interferences with a 5-path interferometer
Thomas Kauten, Robert Keil, Thomas Kaufmann +3
Within the established theoretical framework of quantum mechanics, interference always occurs between pairs of trajectories. Higher order interferences with multiple constituents a…

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…
Broadband indistinguishability from bright parametric downconversion in a semiconductor waveguide
T. Günthner, B. Pressl, K. Laiho +5
Parametric downconversion (PDC) in semiconductor Bragg-reflection waveguides (BRW) is routinely exploited for photon-pair generation in the telecommunication range. Contrary to man…
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…
Measurement and modeling of the nonlinearity of photovoltaic and Geiger-mode photodiodes
Thomas Kauten, Benedikt Pressl, Thomas Kaufmann +1
While in most cases the absolute accuracy, resolution, and noise floor are the only relevant specifications for the dynamic range of a photodetector, there are experiments for whic…
Notes on Evanescent Wave Bragg-Reflection Waveguides
Benedikt Pressl, Gregor Weihs
We investigate an extended version of the Bragg reflection waveguide (BRW) with air gaps as one of the layers. This design has the potential of drastically simplifying the epitaxia…
Multi-dimensional laser spectroscopy of exciton-polaritons with spatial light modulators
P. Mai, B. Pressl, M. Sassermann +6
We describe an experimental system that allows one to easily access the dispersion curve of exciton-polaritons in a microcavity. Our approach is based on two spatial light modulato…
