Low-loss wavelength division multiplexing (WDM) devices for single-mode systems
Journal of Lightwave Technology, 1983We report here on single-mode microoptic wavelength division multiplexing (WDM) devices with two channels located at 1275 and 1345 nm, respectively. Data are presented for four multiplexers and four demultiplexers. The average insertion loss for the multiplexers was 0.5 ± 0.2 and 1.0 ± 0.3 dB for the short and long wavelength channels, respectively ...

Bandwidth Reduction Technique for Multilayer Wavelength Division Multiplexing (WDM) Bandpass Filters
Applied Optics, 2000The push to develop 100 GHz and smaller bandwidth WDM filters is at demanding levels. Currently, 200 GHz is the standard bandwidth for multilayer interference coatings with high efficiencies, and enormous processing effort is going into the development of standard 100 GHz filters. This paper outlines a simple design that will reduce bandwidth up to 40%

Wavelength division multiplexed (WDM) data-block switching for parallel computing and interconnects
SPIE Proceedings, 1998We report a new generation switch, the data-block switch, which can greatly increase the capacity and reduce the complexity of the interconnect network of a parallel computing system. By using WDM techniques, parallel data can be multiplexed and transmitted through a single fiber.

Link failure recovery using p-cycles in wavelength division multiplex (WDM) mesh networks
Journal of Optical Communications, 2020Abstract Network survivability has become a crucial requirement in all types of computer networks. It becomes even more significant for wavelength division multiplex (WDM) mesh networks due to their high speed and capacity. These networks are prone to link failures. A link failure may be a single or multiple link failure.

22nd Digital Avionics Systems Conference Proceedings (Cat No 03CH37449) DASC-03, 2003
MIL-STD-1553 has become the de facto backbone avionics network over the last several decades. Avionics networks incorporating fiberoptic interconnects have recently evolved from point-to-point and ring network link designs with Mb/s LED sources and opto-mechanical switching to higher bandwidth networks based on Gb/s VCSEL sources and opto-electronic ...

Proceedings.Twenty-First Annual Joint Conference of the IEEE Computer and Communications Societies, 2003
We study routing and wavelength assignment for a circuit-switched time division multiplexed (TDM) wavelength-routed (WR) optical WDM network. In a conventional WR network, an entire wavelength is assigned to a given session (or circuit). This can lead to lower channel utilization when the individual sessions do not need the entire channel bandwidth. We
