Enabling Shortwave-QKD in Short-Reach Networks: Impact of a Composite ODN Native to Telecom Applications
Mariana F. Ramos, Costin Luchian, Michael Hentschel +4
We deploy shortwave-QKD over short-reach in-house/datacom architectures and show that few-mode propagation and speckle-selective loss severely impact the QKD performance. We accomp…
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…
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…
