We have developed a simple scheme to implement optical signal to noise ratio (OSNR) monitoring on planar waveguide or arrayed waveguide grating (AWG) based channel power monitoring circuits. Simulation and experiment have demonstrated that our proposal will yield better OSNR monitoring range comparing with traditional tunable filter solutions. The combination of AWG and periodic notch filter makes it more immune to neighbor channel influence, and further improves the OSNR monitoring accuracy.

This paper proposed a packet assembly mechanism and investigated its impact on the network performance under self-similar traffic. The simulation results have demonstrated that this mechanism can serve as a traffic shaper to reduce the network-wide packet-loss rate efficiently. By incorporating the contention resolution schemes in wavelength, time, and space domains, traffic shaping leads to a several-fold benefit of performance improvement at the expense of relatively small increases in delay.

We have succeeded in reducing the drive voltage of a 40Gb/s LiNbO/sub 3/ modulator to 0.9 V, which is the lowest-drive-voltage 40Gb/s LiNbO/sub 3/ modulator in the world. The modulator can be driven within the break down voltage of a SiGe transistor. This result was achieved using a new design concept that featured a wide-gap, long CPW (coplanar waveguide) electrode.

This article showed that the multiple-wavelength Raman fiber laser (MWRFL) is a potential source for stable Raman amplification. It was shown that this source can be configured as a pump for many different fiber types and lengths, and is also stable enough to be used in transmission systems.

In this paper two aspects of optical quality of service (QoS), namely the quantitative measures of the optical signal and the functional requirements such as routing stability and protection were discussed. Transmission impairments-based routing of 40 Gb/s connections was investigated and substantial improvement in bandwidth utilization was demonstrated when traffic was split at the source into 10 and 40 Gb/s connections, that were routed separately based on the quality of the available transmission links. The feasibility of differentiation based on routing stability in integrated traffic engineering was demonstrated using the RITE scheme with the preliminary results indicating substantial potential for better utilization of existing lightpaths. Class-based protection and restoration has been investigated and numerical examples were provided that show how different classes of traffic could be routed in a cost-effective way requiring less protection bandwidth.

We have demonstrated for the first time in our knowledge optical label-based wavelength switching and packet drop over actual field fiber. We have shown SCM-formatted optical labeling transmission with less than 2 dB power penalty for both label and payload over 476 km of fiber. The optical label switching achieves packet drop and re-transmission of the remaining packet.

Summary form only given. The introduction of cross-connects (XCs) into optical networks grants us the opportunity to rapidly provision high bandwidth connections. These connections are generally used to carry critical customer data. As such, connection reliability becomes a major concern for both carriers and their customers. We investigated the scalability of XC architectures and shared-mesh restoration signaling schemes for rapid restoration. The key findings are that: 1. Sequential processing of cross-connect requests is highly undesirable for cross-connects with significant per-node cross-connect times; and 2. Contention resolution schemes with message forwarding only after cross-connection completion (such as those used within current generalized-multi protocol label switching (GMPLS) proposals) provides significantly slower restoration as compared with contention avoidance schemes.

We present a reconfigurable wavelength-selective switch that independently distributes 128 input WDM channels to four output ports. The switch is based on bulk optics and MEMS micro-mirrors, exhibits <5 dB insertion loss and flat-top pass-bands, and is well suited for transparent switching of 10 Gb/s signals.

In conclusion, we used an active injection locking technique to stabilize the output polarization of a fiber DFB laser. By adjusting the operating current and injection power of the Fabry -Perot (FP) LD, we achieved nearly linear polarized output with DOP larger than 95% and SMSR higher than 45 dB. We had also shown that this technique can eliminate the amplitude jitter of an externally modulated DFB-fibre laser, and observed a 3.8 dB power penalty improvement in a 10 Gb/s 41-km transmission experiment. Our results indicate that highly polarized multi-wavelength sources can be realized by injection locking of a single low-cost FP-LD with several fiber lasers.
