The concepts of bandwidth sharing based on optical burst or packet switching appear to be capable of enabling quality of service (QoS) within the physical layer of advanced high-speed networks. However, it is yet to be investigated how these concepts can be integrated with management of higher layers of the telecom infrastructure, to ensure service level agreements end-to-end across various administrative and technology domains. We discuss issues associated with mapping of service management requirements into the intelligent optical IP layer, and analyse interactions between the management plane and control plane in the process of maintaining a guaranteed service over the wavelength-routed optical burst switched network (WR-OBS).

The optical code division multiple access (OCDMA) over wavelength division multiplexing (WDM) passive optical network (PON) system has been proposed as a potential candidate for gigabit-symmetric fiber-to-the- home (FTTH) services. Asynchronous OCDMA over WDM systems have been experimentally demonstrated using superstructured fiber Bragg gratings (SSFBG) and multi-port OCDMA en/decoders. The total throughput has reached above -380 Gbit/s with spectral efficiency of about -0.32.

We investigated strong mode selection scheme in a layered cylindrical microcavity laser with a thin lower refractive dielectric inner coating. We used a fused silica capillary (outer diameter of 320 mum, inner diameter of 250 mum), filled with dye-doped ethanol, as the cylindrical cavity and coated AF 1600 on the inner wall of the capillary in order to change the reflectivity of light at the inner wall. Because whispering gallery modes perturbed (or split) by inner wall, there exist interferential coupling effect whose modulation depth depends on the reflectivity of inner wall. The strongest mode selection was observed at the reflectivity of about 50%, in which corresponding thickness of AF 1600 was about 0.4 mum. Due to the enhanced interferential coupling effect, the lasing spectrum appeared as few periodic peaks just around the wavelengths corresponding to the constructive interference condition. We compared the lasing spectrum with that from a bare capillary and discussed the role of thin dielectric coating on the strong mode selection.

We discuss recent work in quantum communication, and in some details present a bright, narrowband, portable, quasi-phase-matched two-crystal source generating polarization-entangled photon pairs at 809 nm and 1555 nm. We also show how the single-photon quantum channel at 1555 nm and a classical synchronization signal gating the single photon detector at the receiving side can be multiplexed in the same optical fiber of length 27 km by means of wavelength division multiplexers (WDM) having 100 GHz (0.8 nm) spacing between channels. This illustrates how single-photon quantum communication applications is compatible with current high-speed optical networks.

In this study the design of reliable network topologies is applied to a typical metro network scenario. Results show that, with an increasing amount of traffic, ring topologies represent a less attractive solution and, on the other hand, highly connected DWDM mesh networks are required to grant the required level of throughput for bandwidth demanding applications and services.

For critical civil and military missions, the Unmanned Aerial Vehicles (UAVs) are continuously attracting attention. UAVs should collect data for a defined area with a variety of sensors. When these UAVs are operating in swarm formation, the observation area could be increased and it would also be possible to deal with a loss of a UAV. The big amount of data produced by the UAVs requires high date rate connectivity, therefore the free space optical (FSO) communication is suitable. When using FSO links some important issues need be considered, the beam attenuation due the atmosphere on one side and the alignment of the FSO units on the other side. The alignment raises technical challenges in tracking and acquisition. The combination of UAVs with the FSO communication is an interesting investigative scenario and some of the important aspects of this ambitious design are the main focus of this paper.

A key initiative in the deployment of new wireless services is to cost effectively extend and enhance the network's radio coverage. Implementing a Distributed Antenna System (DAS) is a common method of extending radio coverage for multiple operators from multiple base stations to multiple locations. In this paper, how the Radio over Fiber (RoF) techniques can offer technically and economically attractive features compared with other ways to provide coverage is described.
