Chirp in a wavelength converter based on a symmetrical-MZI employing SOAs
Jamro, M.Y.; Senior, J.M.; Leeson, M.S.; Murtaza, G. (2002-08-15)A wavelength converter based on cross-phase modulation using semiconductor optical amplifiers (SOAs) in a symmetrical MZI is modelled. Since the model of the SOAs considers both amplitude and wavelength-dependent parameters ... -
Developments in wavelength division multiple access networking
Senior, J.M.; Handley, M.R.; Leeson, M.S. (1998-12-01)The last few years have seen a growing interest in WDM for optical networks in order to increase capacity and overcome the electronic bottleneck. Alongside the improvement in WDM components there has been continuing ... -
Modeling Chirp and Phase Inversion in Wavelength Converters based on Symmetrical MZI-SOAs for use in All-Optical Networks
Jamro, M.Y.; Senior, J.M.; Leeson, M.S.; Murtaza, G. (2003-05-01)All-optical wavelength conversion based on multi-section semiconductor optical amplifiers (SOAs) in a symmetrical Mach-Zehnder interferometer (SMZI) is modeled for use in optical networks. It incorporates an enhanced SOA ... -
Modelling the response of different WDM PON architectures to varying traffic load
Senior, J.M.; Handley, M.R.; Leeson, M.S.; Phillips, A.J.; Ball, P.; Wright, I. (1999)The introduction of wavelength division multiplexing into the access network is a potentially attractive alternative upgrade strategy to increasing the bit rate of passive optical networks (PON). A number of different ... -
Modified ShuffleNet for Multihop All-Optical WDM Networks Employing Wavelength Reuse
Jamro, M.Y.; Murtaza, G.; Leeson, M.S.; Senior, J.M. (2000)A modified multihop ShuffleNet configuration for WDM all-optical networks is described which is rearrangeable and allows wavelength reuse at each node as it expands. This configuration does not require any rearrangement ... -
New wavelength assignment schemes for wavelength division multiplexed passive optical networks
Senior, J.M.; Handley, M.R.; Leeson, M.S.; Phillips, A.J.; Ainscough, J. (2000)The passive optical network has been shown to be a cost effective method of introducing fibre to the access network. However, the expected increase in demand for broadband services will inevitably mean that upgrades in ...
