Code division multiple access (CDMA) enhancement of wavelength division multiplexing (WDM) systems
Proceedings IEEE International Conference on Communications ICC '95, 2002Wavelength division multiplexing (WDM) is a mainstream technology for optical communications ranging from long haul applications to interconnections between and within high speed digital systems. WDM is, however, constrained (1) in density by the crosstalk associated with channel spacing and (2) by total number of channels which can be uniformly ...

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

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.

Long-Reach Wavelength Division Multiplexing-Passive Optical Networks (WDM-PONs)
ACOFT/AOS 2006 - 31st Australian Conference on Optical Fibre Technology and Meeting of the Australian Optical Society, 2007A bidirectional long-reach 64-channel DWDM-PON with 50 GHz channel spacing based on wavelength-locked Fabry-Perot laser diodes is demonstrated. It consolidates a metro network into an access network by bypassing the central offices within its reach.

Optical Fiber Communication Conference, 2017
We demonstrate an orbital angular momentum (OAM) fiber amplifier and evaluate its performance in an OAM and wavelength multiplexing system. The small signal gain is up to 19 dB from 1530 nm to 1565 nm. The OSNR penalties at a BER of 2e-3 are less than 1.8 dB for all channels.
