Chip-Scale Transmitter Module for Real-Time Continuous-Variable QKD
Igor Servello, Martin Hauer, Moritz Baier +6
Continuous-variable quantum key distribution (CV-QKD) enables secure communication over standard telecom infrastructure, but scaling is stalled by bulky, discrete optical hardware.…
DemoQuanDT: A Carrier-Grade QKD Network
P. Horoschenkoff, J. Henrich, R. Böhn +20
Quantum Key Distribution Networks (QKDN) enable secure communication even in the age of powerful quantum computers. In the hands of a network operator, which can offer its service…
Fabry-Pérot etalon walk-off loss in ring cavities
Ulrich Eismann
Fabry-Pérot etalons are widely used for laser frequency control. Inserting them in laser cavities imparts unavoidable walk-off loss and reduces the output power. Here, we treat the…
Active and passive stabilization of a high-power UV frequency-doubled diode laser
Ulrich Eismann, Martin Enderlein, Konstantinos Simeonidis +6
We present a resonantly frequency-doubled tapered amplified semiconductor laser system emitting up to 2.6 W blue light at 400 nm. The output power is stable on both short and long…
Comment on: Investigation of the thermal lens effect of the TGG crystal in high-power frequency-doubled laser with single frequency operation
Ulrich Eismann
In their article, the authors of [Opt. Express 23, 4981 (2015)] observe step-like behavior and hysteresis of the output power of a diode-end-pumped Nd:YVO 4-laser as a function of…
Universal Loss Dynamics in a Unitary Bose Gas
Ulrich Eismann, Lev Khaykovich, Sébastien Laurent +8
The low temperature unitary Bose gas is a fundamental paradigm in few-body and many-body physics, attracting wide theoretical and experimental interest. Here we first present a the…
