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…
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…
Deterministic positioning of circular Bragg gratings using atomic force lithography for high-performance quantum dot light sources
Sai Abhishikth Dhurjati, Moritz Langer, Yared G. Zena +6
Semiconductor quantum dots (QDs) grown by molecular beam epitaxy are excellent quantum emitters, but their random spatial distribution hinders deterministic coupling to optical mic…
Free-standing circular Bragg gratings enabling efficient GaAs quantum dot entangled photon pair sources
Sai Abhishikth Dhurjati, Moritz Langer, Yared G. Zena +6
Deterministic and bright quantum light sources based on scalable semiconductor technologies are a crucial building block for future quantum communication networks. While circular B…
Compact system development of efficient quantum-entangled photon sources towards deployable and industrial devices
Yared G. Zena, Moritz Langer, Ahmad Rahimi +9
Entangled photon pair sources are a key enabling technology for quantum communication and networking, yet their deployment beyond laboratory environments is hindered by system-leve…
