Unfolding the Hong-Ou-Mandel interference between heralded photons from narrowband twin beams
K. Laiho, T. Dirmeier, G. Shafiee +1
The Hong-Ou-Mandel (HOM) interference is one of the most intriguing quantum optical phenomena and crucial in performing quantum optical communication and computation tasks. Lately,…
Measuring higher-order photon correlations of faint quantum light: a short review
K. Laiho, T. Dirmeier, M. Schmidt +2
Normalized correlation functions provide expedient means for determining the photon-number properties of light. These higher-order moments, also called the normalized factorial mom…
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…
Photon-number parity of heralded single photons from a Bragg-reflection waveguide reconstructed loss-tolerantly via moment generating function
K. Laiho, M. Schmidt, H. Suchomel +6
Due to their strict photon-number correlation, the twin beams produced in parametric down-conversion (PDC) work well for heralded state generation. Often, however, this state manip…
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…
