A single-photon detector with high efficiency and sub-10ps time resolution
Iman Esmaeil Zadeh, Johannes W. N. Los, Ronan B. M. Gourgues +4
The observation of fast physical dynamics using optical techniques currently relies on indirect methods, such as pump-probe measurements. One reason for this is the lack of an effi…
Single-photon detectors combining ultra-high efficiency, detection-rates, and timing resolution
Iman Esmaeil Zadeh, Johannes W. N. Los, Ronan B. M. Gourgues +5
Single-photon detection with high efficiency, high timing resolution, low dark counts and high photon detection-rates is crucial for a wide range of optical measurements. Although…
Design of broadband high-efficiency superconducting-nanowire single photon detectors
Luca Redaelli, Gabriele Bulgarini, Sergiy Dobrovolskiy +4
In this paper several designs to maximize the absorption efficiency of superconducting-nanowire single-photon detectors are investigated. Using a simple optical cavity consisting o…
Avalanche amplification of a single exciton in a semiconductor nanowire
Gabriele Bulgarini, Michael E. Reimer, Moïra Hocevar +3
Interfacing single photons and electrons is a crucial ingredient for sharing quantum information between remote solid-state qubits. Semiconductor nanowires offer the unique possibi…
Bright single-photon sources in bottom-up tailored nanowires
Michael E. Reimer, Gabriele Bulgarini, Nika Akopian +6
The ability to achieve near-unity light extraction efficiency is necessary for a truly deterministic single photon source. The most promising method to reach such high efficiencies…
