Effect of phase noise in Dense Wavelength Division Multiplexing (DWDM) networks

2006 IEEE Region 5 Conference, 2006
In this paper, the phase stability of 50 km externally modulated 256-QAM DWDM fiber optic link is evaluated. The analysis of RF phase noise in the fiber optic link is the main objective of this work. RF phase noise is mainly investigated with preamplifier (EDFA) configuration at 1550 nm wavelength.

16×16 silicon photonic AWGR for dense wavelength division multiplexing (DWDM) O-band interconnects

Silicon Photonics XV, 2020
The rapid increase of bandwidth requirements across the entire hierarchy of Data Center (DC) networks, ranging from chip-to-chip, board-to-board up to rack-to-rack communications, puts strenuous requirements in the underlying network infrastructure that has to offer high-bandwidth and low-latency interconnection under a low-energy and low-cost envelope.

Nonlinear graphene-based nanophotonic switch working in dense wavelength division multiplexing (DWDM) systems

Applied Physics A, 2017
Fiber-based devices for operation in fully optical networks are relatively large in size and can not be used in photonic integrated circuits (PICs). We have developed an efficient graphene-based nanophotonic switching nanocell, working in linear regime (cross state) and in non-linear regime (bar state) with relatively low optical power, so that they ...
