Arrayed electro-optic modulators for novel WDM multiplexing
Scientific ReportsIn this paper, a novel silicon-on-chip integrated 4 × 1 wavelength division multiplexing (WDM) multiplexer has been developed. This is the first time that the multiplexer design incorporates arrayed electro-optical modulators with crosstalk cancellation.

Scaling WDM Slotted Ring Networks
, 2007 Using analogies between the basic theory of cell switching for datagram networks and multiwavelength slotted optical networks, we show that the buffering capabilities of high-speed slotted networks, also known as spacereuse, allows multihop networks such

Integration of QKD in WDM networks
2021 International Conference on Optical Network Design and Modeling (ONDM), 2021The theme of the integration of Quantum Key Distribution (QKD) in existing WDM optical networks will be discussed. Some evaluations about a reduced-cost implementation of BB84 protocol for QKD will be presented, where a QKD channel in O band is added to classical C-band WDM channels in the same fiber.
