- Abstract
We prove micro-ring resonator assisted DPS-QKD as multi-wavelength alternative to delay-interferometer based implementations. We show wavelength-agnostic generation of secure keys over 13 WDM channels ranging from 1534.3 to 1555.3nm. We further demonstrate simultaneous QKD operation over 12.8km, for which two users shared the state analyser.
