Temperature-dependent refractive index of AlGaAs for quantum-photonic devices near the bandgap
Moritz Langer, Sai Abhishikth Dhurjati, Martin Bauer +6
We present an experimental method to determine the refractive index of (x = 0.0 - 0.5) from 300 K to 4 K across the 500 - 1100 nm wavelength range. The values ar…

An ultra-compact deterministic source of maximally entangled photon pairs
M. Langer, P. Ruchka, A. Rahimi +9
We present an ultra-compact source of maximally entangled on-demand photon pairs. Our results are based on coupling of single GaAs quantum dots that are embedded in monolithic micr…

Bright quantum dot light sources using monolithic microlenses on gold back-reflectors
Moritz Langer, Sai A. Dhurjati, Yared G. Zena +8
We present the fabrication process of bright quantum dot (QD) photon sources by non-deterministic embedding into broadband monolithic microlens arrays…
