While today's WDM optical networks are mostly based on 10 Gbit/s data, modulated according to the nonreturn-to-zero (NRZ) format, networks at 40 Gbit/s and beyond will likely use more complex modulation formats, possibly involving more than 1 bit/symbol. For these formats, conventional quadratic detection techniques appear less practical, while the coherent detection technique looks more appealing. The latter provides the real and imaginary parts of the signal, at the expense of a larger complexity and cost. These drawbacks should be weighted by the promises offered by the technique when combined with advanced digital signal processing (DSP). DSP not only solves some severe implementation issues, but also holds in store a tremendous potential against fibre impairments. We will demonstrate experimentally that a coherent receiver involving DSP can mitigate distortions from chromatic dispersion, from polarisation mode dispersion and from narrow optical filtering, even after several thousand kilometres of fibre, thereby paving the way for higher-capacity, longer-reach transparent optical networks.

Optical fibre is marching fast towards the user's doorstep, as witnessed by the many new Fibre-To-The-Home installations. The next challenge is to disclose the power of optical communication inside the home, so to bring the full broadband potential to the end user. The presentation will describe the latest advances in our research into low-cost in-home techniques, encompassing techniques for service integration, for high-speed data transfer over highly dispersive polymer optical fibre, and for dynamically providing high-capacity wireless services over fibre.

Thresholds of lasing for a cavity with a quantum well placed between two distributed Bragg reflectors are investigated as a specific eigenvalue problem with "active" imaginary part of the quantum well refractive index. The characteristic equation is obtained from the transmission-matrix formalism. Preliminary results show that the frequencies of lasing are determined mainly by the size and material of the cavity, and the thresholds are sensitive to the quantum-well size and location and can be lowered by the proper tuning of the Bragg reflectors.

This paper evaluates and compares the performance of Grid over Optical Burst Switching (OBS) networks employing Active routers. Two signaling reservation schemes are considered: the Just Enough Time (JET) and a centrally controlled Wavelength Routed (WR) scheme. Analysis and simulation results show that the centrally controlled WR-OBS signaling scheme always outperforms the JET-OBS scheme in terms of job blocking rate and the time delay that a job suffers until it reaches the Grid service provider.

We theoretically and experimentally report on fast self-focusing of light in a photorefractive semiconductor. In these applications, semiconductor materials are very attractive considering their high sensitivity at telecommunication wavelengths (1.55 mum), short response time and memory effect. Photorefractive self- focusing and soliton interactions lead to self-induced and reconfigurable semiconductor waveguide which would find interesting applications in optical communications, optical routing or interconnections.

We fabricated quasi-stadium laser diode which has a 'window' on the top of cavity by ion-etching technique to epitaxial wafer and demonstrated to observe direct lasing mode observation. In the carrier poor region, bright line can recognize. On the other hands, in the rich carrier region, lasing pattern was recognized as dark line. Both lines well fit extended Fox-Li simulation. From these results, it can understand that the lasing pattern condition depend the carrier density.

In this paper we present a hybrid opto-electronic switch architecture, which can be enhance the performance of optical packet switching (OPS) schemes. The proposed architecture is based on the use of electronic line-cards and packet cross-connect to a limited degree utilizing the large buffering capacity available only by means of electronic subsystems. This hybrid architecture achieves efficient utilization of optical network resources, which can be assigned dynamically in small time scales, limiting loss probability with controlled average latency.
