Objective
The main objective is to bring to full maturity key advanced components and modules for photonic networks and to demonstrate their practical use in systems. A large number of specific targets are set for component performance. Demonstration of practical applications will be carried out within the project as well as in other ACTS projects.
The project expects to demonstrate improved component performance, improved scope for low cost manufacturing, as well as practical applications of advanced optical components.
Among the results to date are:
Worlds first monolithically integrated InP based reconfigurable add-drop multiplexer
Compact low-loss polarisation insensitive phased array demultiplexer
Development of tuneable lasers with complete coverage of the 1550nm window
Demonstration of a wavelength programmable source
Demonstration of 20Gbit/s all optical demultiplexing using a monolithically integrated non-linear Sagnac interferometer
Laser flip-chip mounting for passive fibre alignment and high speed operation
Definition of a software environment and documentation structure for automated characterisation and parameter extraction, including options for remote characterisation.
Monolithically integrated non-linear Sagnac interferometer for OTDM.
Expected Impact
By addressing improved functionality and cost-effectiveness for photonic modules, the project will assist in providing access to IBC networks for private and business users and aims to demonstrate the potential for high capacity services such as multimedia and video conferencing.
Main contributions to the programme objectives:
Main deliverables
A reference model for Interactive Satellite Broadcasting via SMATV installations and a demonstration of such a service.
Contribution to the programme
Development of inexpensive broadband access for Interactive Multimedia Services.
Technical Approach
A 4 x 2.5Gbit/s WDM long-haul transmission system demonstrator will be defined, assembled and evaluated, and a 3-node WDM field trial in a combined core and access network will be carried out.
Specific demonstrators will include a cross-connect in which the influence of specific device properties will be studied in detail (optical crosstalk, optical dynamic range, optical monitoring).
The implementation of OEIC receiver chips in the Access Area will be addressed in two technical approaches, namely a PON and an ATM ring solution. A comparison between OEIC and commercial transceivers will be done in an ATM ring field trial, and the impact of OEICs will be verified.
In addition work will lead to realisation of a heterodyne spectrum analyser, which requires a widely tuneable laser with complete wavelength coverage (target 40nm), and a coherent optical time domain reflectometer which requires simultaneously a narrow line and wide tuning.
The project will develop the following range of key components and evaluate their performance in demonstrators:
A WDM demultiplexer module.
Multi-wavelength lasers using a phased array design.
Photonic ICs for the optical cross-connects.
OEIC transceiver chip fabrication.
Packaging technology for OEICs.
Development of design and modelling tools for OEICs.
A monolithic high-speed short pulse source.
Tuneable lasers (30nm range), operating at 2.5Gbit/s.
Lasers which allow the operating wavelength to be set at the time of installation.
Semiconductor optical amplifiers for PON and WDM applications and non-linear interferometers.
Uncooled 1.55m complex coupled DFB lasers operating at 2.5Gbit/s.
Tapers for improved coupling efficiency and alignment tolerance.
Automated measurement procedures and tools.
The Oslo network.
Summary of Trial
An access network demonstrator will be based on the realisation of a universal interface for different types of traffic (e.g. N x 64kbit/s CBR, ATM-VBR) and different physical media (fibre, copper, etc) to provide ATM access within the customer premises network and the public access area. This solution will aim primarily at the business area.
WDM will be addressed in laboratory demonstrators and a 3-node field trial to demonstrate increased flexibility and reconfigurability by exploiting the optical fibre as a transparent medium for simultaneous transmission of different signal formats and services.
An optical cross connect demonstrator will be realised using commercial components and transmission systems in order to evaluate the functionality of the configuration and to provide a test-bed for control and management protocols. The commercial components will be replaced by integrated equivalents and the performance in the network evaluated.
Components from BLISS will be used in trials of other ACTS projects including UPGRADE, WOTAN, and BROADBANDLOOP.
Add-drop multiplexer and Sampled Grating DBR laser.
