We have demonstrated a bidirectional PON for the transmission of 2.5-Gbps WDM channels and >70 digital broadcast video signals. This network could be implemented cost-effectively using a single strand of fiber for bidirectional transmission, LEDs for upstream channels, and one receiver for the detection of both the video and baseband signals (5622 Mbps). In addition, the capacity of the proposed network could be upgraded easily by changing the RF filter or using an additional WDM filter and a receiver.

In this work we demonstrate the HORNET 2FBPSR survivable architecture and the associated protocols. With simple intuition, we can see that this architecture performs up to twice as well as that of conventional ring architectures under normal conditions, and in the worst case the performance is equal after a cut occurs. We experimentally demonstrate that when a cut occurs, the maximum amount of time that any two nodes lose the ability to communicate is equal to the propagation delay of the fiber between them (less than 1 ms for a typical metro ring architecture). The demonstration of the HORNET testbed presented here is a major step towards making next generation high capacity packet-based MANs a reality.

In summary we fabricated and characterized integrated differential photodetector modules with 35 GHz and 45 GHz electrical bandwidth. The devices show total responsivities of 0.41 A/W and 0.31 A/W respectively and PDL of less than 0.5 dB. The ratio of the photocurrents remains below 0.5 dB for different states of polarization demonstrating an excellent electrical and optical symmetry. The modules deliver high electrical output pulses of differential polarity in the 1 Volt regime to switch directly all known 40 Gbit/s demux electronics implemented in SiGe, GaAs or InP technology.

We have demonstrated an advanced 160 Gbit/s OTDM transmission system with a wavelength transparent transmitter concept suitable for DWDM operation. Latest 40 Gbit/s ETDM technology is used for the first time both in the 160 Gbit/s transmitter and receiver along with PLL clock recovery. 160 Gbit/s OTDM transmission has been demonstrated over 2 /spl times/ 100 km of TeraLight/spl trade/ fibre without an error floor. The experiments clearly show that long TeraLight/spl trade/ fibre spans can be bridged without the need for Raman-amplification.

Summary form only given. We demonstrated the usefulness of a new technique for making time-resolved measurements of BER and OSNR. As an example, we measured the OSNR and the BER of a surviving channel as the channel loading was varied by 100%. A severe drop of 5 dB in OSNR was observed despite the fact that the channel power decreased by 3 dB only.

We have demonstrated that a uniform fiber Bragg grating can be used in reconfigurable OCDMA phase-encoding/decoding applications by deploying fine heating elements at equal intervals along the fiber grating. One single fiber Bragg grating comprising the device, offers the advantages of compactness and low fabrication complexity, and we demonstrate its application in an 8-chip 20 Gchip/s bipolar configuration.

In conclusion we have demonstrated fully nonblocking 16/spl times/16 switches in a single chip solution using MEMS fabricated by a surface micro-machining. We have shown how the critical mechanical elements of the MEMS-cell have been chosen to achieve large mechanical movement, high angular repeatability of the movement, and high reliability of the actuation mechanism, which translated into low loss and high reliability of the packaged component. Test results for these components have been presented.

We have demonstrated a compact optical packet synchronizer. With a tunable DBR LD and SOA gates, the synchronization is successfully achieved with simple electric circuits by controlling the switching timing. Because OFCs are used, the OPSy is compact and the delay time can be controlled precisely. in this architecture, by increasing the number of wavelengths, finer resolution can be obtained without much increase in the losses and crosstalk.
