We demonstrate a mitigation of Rayleigh back-scattering (RBS) impact in 10-Gb/s reflective electroabsorption modulator monolithically integrated with semiconductor optical amplifier (REAM-SOA). The technique is based on the intensity-noise suppression of the centralized incoherent seed-light, which enables smooth evolution of deployed DWDM applications. We exhibit the power penalty of less than...

Service providers are currently adopting coherent transceivers for their 100G DWDM backbone applications to achieve the higher capacity and longer fiber reach that coherent technology offers. Coherent transceivers also provide costeffective electronic equalization of fiber impairments – such as chromatic dispersion and polarization-mode dispersion – as well as extensive performance monitoring c...

Silicon nanophotonics holds the promise of dramatically advancing the state of the art in computing by enabling parallel architectures that combine unprecedented performance and ease of use with affordable power consumption. This paper presents a design study for a manycore architecture called Corona which utilizes dense wavelength division multiplexing (DWDM) for onand off-chip communication t...

-In this paper the origins of crosstalk in DWDM millimetre hybrid fibre radio networks are discussed. A means by which polarisation interleaving might be implemented with a view to reducing the impact of crosstalk is explained analytically. It is concluded that with standard fibre and continuous wave transmission polarisation interleaving provides little benefit if used over distances greater t...

A novel technique to overcome the long-term drift and hysteresis of a scanning Fabry–Perot filter was developed and applied to wavelength and power monitoring of DWDM system. By using the comb peaks generated by a temperaturestabilized, near threshold-biased Fabry–Perot diode laser as wavelength reference for the scanning Fabry–Perot filter, wavelength and power measurement accuracy of better t...

We discuss service delivery aspects in a reconfigurable photonic access network. The network is viewed as a stack of logical PONs in which a DWDM overlay is used over TDM PONs operating in their native format. The use of optical routers in the network allows for a dynamic change in the network topology to optimize the bandwidth delivery to end users. The issues related to providing services to ...

IP over Optical is being envisioned as one of the most attractive architectures for the new Internet. There have been various proposals in IETF and other international standards organizations regarding the interaction of IP routers and Optical core networks. This paper describes the architectural alternatives for the integration of IP and DWDM networks using Multiprotocol Lambda Switching (MPLa...

Dense Wavelength Division Multiplexing (DWDM) enables the utilization of a significant portion of the available fiber bandwidth by allowing many independent signals to be transmitted simultaneously on one fiber, with each signal located at a different wavelength. In this paper, the two major non-linear effects such as FWM and SRS in transmission fiber must be simultaneously eliminated by Duobin...

A configurable optical add-drop multiplexer (OADM) based on fibre Bragg gratings is reported. Dynamically selection of the add-drop or pass-through functionality is realised according to the control of an optical switch. The OADM performance measurement realised in a 70 km, 3 × 2.5 Gb/s channels dense wavelength division multiplexing (DWDM) experimental network are reported and the results comp...

This paper is a report of the panel session of the same name held at the 1 st International Workshop on Data Warehousing and Data Mining (DWDM'98) held in Singapore in November 1998. The purpose of the panel was to discover the views of researchers in the field in order to encourage research in data warehousing and data mining to be directed in the most profitably manner and to discuss issues r...
