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…
