Shortwave DPS-QKD Employing a SiN Micro-Ring Resonator as Compact Quantum State Analyser
Florian Honz, Paul Müllner, Michael Hentschel +6
We show simplified DPS-QKD using a SiN micro-ring resonator operated at 852 nm. A raw-key rate of up to 25.3 kb/s is reached at a QBER suitable for secure-key extraction. Short-rea…
Large-Core Optics for Simplified Short-Range FSO Links
Florian Honz, Bernhard Schrenk
We evaluate large-core FSO links where excellent coupling pairs with bandwidth fading due to multi-mode propagation. The 10-Gb/s/λ limit for 105-μm double-clad fibers is mitigated…
First Demonstration of a Group-IV Emitter on Photonic BiCMOS Supplying a Quantum Communication Link
Florian Honz, Michael Hentschel, Stefan Jessenig +3
We implement a silicon-on-insulator light emitter as optical supply for a QKD transmitter and transfer it to an electronic BiCMOS wafer. A secure key is established over short reac…
Solar-Blind QKD over Simplified Short-Range FSO Link
Florian Honz, Michael Hentschel, Philip Walther +2
We demonstrate QKD and data communication over an out-door free-space link where large-core fiber substitutes active alignment. We further prove E-band QKD as stable and robust und…
Towards an All-Silicon QKD Transmitter Sourced by a Ge-on-Si Light Emitter
Florian Honz, Nemanja Vokić, Michael Hentschel +3
We demonstrate a novel transmitter concept for quantum key distribution based on the polarization-encoded BB84 protocol, which is sourced by the incoherent light of a forward-biase…
First Demonstration of 25λ x 10 Gb/s C+L Band Classical / DV-QKD Co-Existence Over Single Bidirectional Fiber Link
Florian Honz, Florian Prawits, Obada Alia +11
As quantum key distribution has reached the maturity level for practical deployment, questions about the co-integration with existing classical communication systems are of utmost…
