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…
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…
