A record high modulation bandwidth of over 50 GHz has been achieved for EAM-DFB lasers in the chip-on-carrier level by optimizing the device parameters. The packaged module has shown a record high modulation bandwidth of 45 GHz and dynamic extinction ratio of 9 dB at Vpp of 3.9 V. The 40 Gb/s NRZ-signal 4 km-transmission with standard SM fiber has been demonstrated. This 40 Gb/s EAM-DFB module is believed very promising for 40 Gb/s short distance fiber transmission.

We present the first electro-mechanical nanophotonic optical switch. A bi-state photonic band gap (PBG) structure was dynamically driven by a MEMS actuator to control the light propagation. An extinction ratio of 11 dB was demonstrated between the transmission state and reflection state for 1.56 /spl mu/m wavelength.

In this paper, we demonstrated the physical feasibility of a transparent waveband-based DWDM metropolitan ring network with 10 nodes and different fiber spans between nodes. it operates at 32 /spl times/ 10 Gbit/s per fiber over up to 155 km TeraLight/spl trade/ Metro fiber in an experiment which is representative of a real metropolitan network. Such a network is cost effective thanks to demultiplexing and switching cost sharing between the wavelengths gathered in wavebands, thanks to amplification cost sharing between nodes (one double-stage EDFA for two nodes is achievable), and thanks to TeraLight/spl trade/ Metro fiber which avoids to use dispersion compensated fibre (DCF) modules for more than 150 km of transmission.

We have demonstrated a high-performance InGaAs-on-silicon APD that exhibits a very low dark current density of 0.7 mA/cm/sup 2/, high avalanche gain (M/spl Gt/100), an RC-limited bandwidth of 1.45 GHz, and a gain-bandwidth product of 290 GHz. We estimate that our device can achieve a sensitivity improvement of 5 dB compared to state-of-the-art InP-based APD receivers. We are currently measuring the APD excess noise factor. We will report this measurement at the conference.

In this paper we report a fully integrated high power, low noise figure EDFA with DGE and OCM (optical channel monitor) utilizing an imbedded controller and fast control algorithm converging in seconds (limited by OCM response time). The EDFA/DGE is used to demonstrate system margin enhancement in a 24 X 40 Gb/s WDM consisting of 7 EDFAs with 200 km of fiber having 8 dB channel power ripple at the end of transmission line. It is shown that DGE enhances system margin, improving the Q-factor by 2 dB for the worst channel.

Summary form only given. We have demonstrated, for the first time to our knowledge, operation of a novel Q-switched erbium doped fiber laser using a fiber Bragg grating placed in loop mirror (FBGLM) as an all-fiber wavelength-selective intensity modulator. The main advantage of this FBGLM modulator is that it provides not only the ability to adjust the reflectivity of the cavity mirror but also the ability of wavelength selection. Stable optical pulse output with 3 dB linewidth of 0.07 nm, pulse width of 1.0 /spl mu/s, and peak power of 1.267 W at 80 mW pump power and 8 KHz repetition frequency was obtained in experiments.

We have demonstrated the generation of a time and wavelength-interleaved pulse train from a fiber ring laser incorporated with a semiconductor optical amplifier. The laser switches at 4 GHz among 4 wavelength components with less than 1.1 dB variation in the optical power. The successful implementation of this scheme indicates the potential to generate a user-defined multiwavelength pulse train from a fiber laser, which is of great importance in WDM communications and photonic ADCs.

We presented a study of power transients in transparent optically amplified networks arising during reconfiguration or protection switching. Besides the well known temporal and spectral EDFA gain dynamics, the stimulated Raman scattering was taken into account. In contrast to the sufficiently fast controllable amplifier gain ultrafast changes of the spectral Raman tilt accumulate along the fiber spans. The resulting uncompensated power spikes limit either the reach of the WDM-system or its dynamics switching capabilities.

The request scheduler carrying out the QoS provisioning with service differentiation was analysed for the wavelength-routed OBS network architecture. QoS performance for two traffic classes was analysed in terms of the burst blocking probability and end-to-end delays and as a function of the constraint of core wavelength over-provisioning. The results show that the WROBS is capable of a very efficient QoS performance, whilst significantly minimising the core wavelength requirement with regards to the statically-routed networks. It is demonstrated that the QoS provisioning for the premium traffic does not trade off the blocking probability of the best-effort traffic. Moreover, even with no core wavelength over-provisioning in WROBS, the desired blocking probability can be achieved for both premium and best-effort traffic whilst the delay bounds for both classes are not exceeded. The reported results are directly applicable for the provisioning of the guaranteed IP services and for RWA optimisation.
