World's First Monolithic SiGe QKD Transmitter Chip
Florian Honz, Winfried Boxleitner, Mariana Ferreira-Ramos +4
We present a single-chip photonic QKD transmitter fabricated on a silicon platform. We achieve secure-key generation over 45.9km of field-deployed fiber and prove its operation alo…
Fiber-Based Focal Plane Array Beamformer as Air Interface of an Alignment-Tolerant Optical Fi-Wi-Fi Bridge
Florian Honz, Bernhard Schrenk
We demonstrate robust light coupling between two single-mode fibers for an out-door FSO link through a focal plane array beamformer with 61 fine-pitched fiber cores as antenna elem…
Alignment-Tolerant Optical Fi-Wi-Fi Bridge Assisted by a Focal Plane Array Beamformer as Air Interface
Florian Honz, Bernhard Schrenk
Terrestrial free-space optical (FSO) links are an ideal candidate to extend the bandwidth continuum offered by fiber networks, yet at the expense of unfavorable cost credentials du…
Bidirectional and Turbulence-Resilient Fi-Wi-Fi Bridge
Florian Honz, Bernhard Schrenk
We present a full-duplex 10Gb/s FSO bridge between two single-mode ports, utilizing centralized beamforming and simultaneous channel sounding. We further mitigate turbulence-induce…
FPA Beamforming for Alignment-Tolerant FSO QKD Links
Florian Honz, Winfried Boxleitner, Michael Hentschel +3
We demonstrate focal plane array beamforming for semi-blind deployments of free-space optical QKD links. We accomplish a secure-key rate of 1.2 kb/s at a QBER of 9.1% over a 63-m o…
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…
