We have demonstrated 80 Gb/s WDM-OTDM transmultiplexing by use of an nonlinear optical loop mirror (NOLM). The penalty after transmultiplexing is 3.3 dB and the OSNR is larger than 25 dB. With the optimization of the signal source as well as the NOLM parameters, the technique can be extended to 160 Gb/s WDM-OTDM transmultiplexing.

We proposed a serial-to-parallel conversion scheme for optical packet header processing. All-optical recognition of a three-bit packet header was demonstrated. The obtained parallel optical signal from the converter can be detected by low speed photodetector array, and can be used as switching control signal for the optical packet switch in a self-routing network node.

We describe a method to significantly decrease insertion loss in waveguide-based devices, including optical cross-connects. Reductions as large as 3 dB are obtained in 32/spl times/32 switches by optimizing the dielectric perturbations.

We experimentally show the system impact of group-delay ripple on system performance when considering a single fibre Bragg grating (FBG) and cascaded FBGs. We find that, for single gratings with different GD ripple, shorter pulse-widths can reduce the penalty induced by GD ripple, meanwhile, the impact of ripple becomes more and more serious as the data rate increases.

Signaling using oDQPSK offers great potential for application in 10 and 40 Gb/s DWDM transmission systems, offering increased spectral efficiency, relaxed dispersion management and improved PMD tolerance. Practical realization of encoder and decoder functionality through integration should lead to wide system application.

Fiber coupled light output power of highly reliable single mode laser diodes with an emission wavelength of around 980 nm has been increased by 40% as compared to former results. The devices reach in excess of 1.3 W ex-facet CW light output power with up to 60% power conversion efficiency and exhibit a vertical far-field of around 21/spl deg/. The maximum fiber coupled CW light output power amounts to more than 700 mW. The devices are designed to satisfy the stringent requirements of future cost efficient uncooled applications as well as the high power market of broadband multi channel networks.

We have reviewed experimental and numerical results on electrical signal processing for the reduction of penalty induced in the optical domain. Since a few years integrated electronic equalizer circuits are available for 10 Gb/s operation. Penalty reduction of signal distorted by chromatic dispersion, PMD, and self-phase modulation has experimentally been demonstrated. First studies on equalization of DWDM typical crosstalk have already been conducted. Nevertheless, as compared to the decade long experience with dynamic equalization of thermal noise limited signal, for amplified optical signal limited by the optical signal-to-noise-ratio (OSNR) the residual penalty after equalization roughly doubles and the fast responding LMS adaptation leads to a sub-optimum setting of the equalizer failing the optimum by up to 0.8 dB which can be avoided by the slower steepest-descend scheme which optimising Q-factor related criteria at equalizer output.

In summary, a multi-service node based on an optical MEMS crossconnect switch with 1.33 dB mean loss has been demonstrated. While a simple 16-wavelength, channel-equalizing add/drop multiplexer was demonstrated as a possible node configuration, a broad range of new functions can be implemented by connecting conventional and different optical components to the low-loss crossconnect switch.

This paper first described design guidelines of multi-wavelength-band WDM transmission systems that avoid the degradation caused by inter- and intra-wavelength-band nonlinear interactions. The guidelines indicate the best combination of wavelength bands for realizing triple-wavelength-band WDM transmission. After discussing the performance of multi-wavelength-band WDM transmission systems, a 1000-channel WDM carrier generator was demonstrated for realizing advanced triple-wavelength-band WDM transmission systems.
