In this paper we describe the performance of the Multiplexer/Demultiplexer (MUX/DEMUX) in the Dense Wavelength Division Multiplexer (DWDM) technology based on arrayed waveguide grating (AWG). The accumulated crosstalk in large-scale AWG solved by the cascade-connection of small AWGs.

Dense wavelength division multiplexing radio-on-fiber systems
MWP 2003 Proceedings. International Topical Meeting on Microwave Photonics, 2003., 2005Dense wavelength division multiplexing (DWDM) millimeter-wave radio-on-fiber (ROF) systems are presented, in which we will focus on its multiplexing and demultiplexing techniques and photonic frequency conversions. The 25 GHz-spacing, 60 GHz-band DWDM ROF is experimentally demonstrated.

Sparsely-Filled Densely-Wavelength-Division-Multiplexed Networks
Photonics in Switching, 1993It has been clear for some time that optical fibre transmission systems have the potential to carry vastly greater amounts of traffic than they are currently used for. For example, in Fig.1, we show typical values for the insertion loss of a 50km fibre section in the 1500nm window and overlay it with an approximate representation of an Erbium Doped ...

A Maxmin Routing Algorithm for Dense Wavelength Division Multiplexing Networks
2006 International Conference on Communication Technology, 2006In this paper, we present an algorithm to solve the routing problem for wavelength division multiplexing networks. We use the discrete maxmin fairness as the routing metric. First we use this algorithm to solve routing problem. After we get paths for all flows in the network, we use another algorithm d-CPG in [1], to assign discrete maxmin rates for ...

Grating spectrograph in InGaAsP/InP for dense wavelength division multiplexing
Applied Physics Letters, 1991A grating spectrograph in InGaAsP/InP suitable for use in the wavelength region from 1.2 to 1.6 μm is presented. Experiments for devices with a channel spacing of 3.7 nm and more than 30 channels between 1.48 and 1.59 μm are described. The measured cross talk level is below −25 dB. The devices have only very low polarization sensitivity.

Architectural tradeoffs for reconfigurable dense wavelength-division multiplexing systems
IEEE Journal of Selected Topics in Quantum Electronics, 2006Advances in optical technology now allow practical reconfigurable wavelength networks to be constructed. These networks use wavelength-switching components to dynamically route wavelengths, and provide a level of flexibility and scalability previously not possible.

Dense Wavelength Division Multiplexing Networks: Principles and Applications
2009The very broad bandwidth of low-loss optical transmission in a single-mode fiber and the recent improvements in single-frequency tunable lasers have stimulated significant advances in dense wavelength division multiplexed optical networks. This technology, including wavelength-sensitive optical switching and routing elements and passive optical ...

A frequency stabilization arrangement for dense wavelength division multiplexing systems
IEEE Photonics Technology Letters, 1992A frequency stabilization scheme using a tunable twin-guide (TTG) laser diode and a Bragg grating filter on a passive waveguide is proposed. This arrangement is fully compatible with the technologies of monolithic integrated optics. The concept was tested in a hybrid assembly.
