We propose a multi-dimensional LDPC-coded-modulation-scheme to achieve high-transmission rates of 320Gb/s and beyond. This scheme utilizes currently-available commercial components operating at 40 Giga-symbols/s, and can reach 400Gb/s aggregate rate with a coding gain of 10.75dB.

Next-generation all-optical packet-switched core networks use very small packet buffers. We argue that it is essential to focus on burstiness rather than bandwidth when conditioning traffic for effective network operation.

An all-optical method to enhance confidentiality in optical networks is presented. Security of a P2P OCDMA transmission is analyzed, where data are scrambled by a cascade of encoders, so that the decryption difficulty is increased.

We study the performance of an adaptive weighted channel equalizer for non-compensated OFDM transmission systems and show that it improves the BER and can reduce the overhead and sensitivity to drifts in the optical channel.

We experimentally demonstrate a flexible electronic compensator for Group Velocity Dispersion induced time skewing in multi-wavelength Optical CDMA systems. The compensator uses a distributed transversal filter already proposed in the context of Optical Communications. Results show improvement in the ability to detect the autocorrelation peak in presence of Multi-Access Interference.

The performance of asynchronous coherent time-spreading OCDMA systems is evaluated semi-analytically and the results are compared with those of spectral coding OCDMA systems using ultra-short pulses. The fundamental multi-access interference limited performances are predicted to be identical.
