In this thesis research, a novel scheme to implement quantum key distribution based on multiphoton entanglement with a new protocol is proposed. Its advantages are: a larger information capacity can be obtained with a longer transmission distance and the detection of multiple photons is easier than that of a single photon. The security and attacks pertaining to such a system are also studied. / Lastly, a quantum random number generator based on quantum optics has been experimentally demonstrated. This device is a key component for quantum key distribution as it can create truly random numbers, which is an essential requirement to perform quantum key distribution. This new generator is composed of a single optical fiber coupler with fiber pigtails, which can be easily used in optical fiber communications. / Next, a quantum key distribution over wavelength division multiplexed (WDM) optical fiber networks is realized. Quantum key distribution in networks is a long-standing problem for practical applications. Here we combine quantum cryptography and WDM to solve this problem because WDM technology is universally deployed in the current and next generation fiber networks. The ultimate target is to deploy quantum key distribution over commercial networks. The problems arising from the networks are also studied in this part. / Quantum cryptography, as part of quantum information and communications, can provide absolute security for information transmission because it is established on the fundamental laws of quantum theory, such as the principle of uncertainty, No-cloning theorem and quantum entanglement. / Then quantum key distribution in multi-access networks using wavelength routing technology is investigated in this research. For the first time, quantum cryptography for multiple individually targeted users has been successfully implemented in sharp contrast to that using the indiscriminating broadcasting structure. It overcomes the shortcoming that every user in the network can acquire the quantum key signals intended to be exchanged between only two users. Furthermore, a more efficient scheme of quantum key distribution is adopted, hence resulting in a higher key rate. / Luo, Yuhui. / "January 2005." / Adviser: K. T.

For packet-switched metro networks, one of the key functional blocks is the transmission, extraction and update of in-band packet control information, which is commonly known as packet label swapping. The use of phase modulation to carry the control information can facilitate easy swapping process. By combining phase modulated label with intensity modulated optical packets in non-overlapping manners, we demonstrated that optical packet label swapping using differential phase-shift keyed labels could be achieved without any sacrifices in packet signal quality. / In packet-switched optical networks, packets are routed using IP-based distributed routing algorithms. Inconsistencies in routing information among routing nodes may result in routing loop formation in the network and may cause severe impact on the network performance. We proposed a novel packet routing loop mitigation scheme based on the principle of packet 'time-to-live' value countdown. This scheme enables loop mitigation to be performed asynchronously in optical domain, causing little packet processing delay. Two implementations were proposed. One was based on differential optical phase shift keying and the other was based on self-phase modulation in semiconductor optical amplifier. / The continuous increase in Internet-bound data traffic in recent years has placed higher requirement on network bandwidth and flexibility. In view of this, packet-switched metro networks and broadband passive optical access networks have emerged as the promising network solutions in the near future. The focus of this thesis is on the improvement of functionality and reliability as well as the reduction of system complexity in optical metro area and access networks with the use of optical phase modulation techniques. In access network, constant-intensity optical phase modulation formats were studied for their applications in wavelength-division-multiplexed passive optical networks with centralized light source. Using them as downstream modulation formats, the downstream optical carrier can be utilized to carry upstream intensity-modulated data. It can greatly simplify upstream transmission and facilitate network management. Experimental and numerical analyses shows promising upstream re-modulation performance with a simple optical network unit (ONU) configuration. / Hung Wai. / Adviser: Lian-Kuan Chen. / Source: Dissertation Abstracts International, Volume: 70-09, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2004. / Includes bibliographical references (leaves 130-135). / Electronic reproduction.

Optical buffers are essential components of future optical switches for resolving contentions among arriving packets. Currently, optical buffers are composed of Fiber Delay Lines (FDL). Unlike the conventional electronic buffer, optical buffer only has finite time resolution, which introduces a void period between two successive buffered packets. The void period leads to service interruptions and deteriorates the buffer performance. We develop a queueing system with exceptional service for the first packet in each busy period to model the buffer behavior. For the first time, the closed-form expressions of packet blocking probability and mean delay of optical buffer are derived. We show that the packet blocking probability can be minimized by finding the optimal FDL time granularity. This optimal granularity is neither sensitive to packet length distribution, nor sensitive to the buffer length, it is mainly determined by the traffic load. / Service interruption is a special case of varying service rate. A current trend in wireless communication is to enable devices to operate using many different transmission rates. This motivates us to develop the queueing models with varying service rate. We apply the continuous time Markov chain to characterize the service rate varying process, and develop a queueing system with Markov-modulated service rate. In this kind of problem, due to the complex interaction between the rate varying process and packet arrival process, it is hard to characterize the server state evolvement; this makes it difficult to get an analytical solution, even the server only has two service rates. To escape the trap, first, we develop a discrete time Markov chain to model the server state transition process, which makes our problem to be easily manipulated. Second, apart from the previous methods, we concentrate on the moments of the packet number in system. We find the recursive relationship between the moments of packet number, this fundamental relationship widely exists in the birth-death queue systems. Our results provide a new methodology to the design of communication systems with varying service rate. / This thesis is aimed to study the interaction between service interruption and the operation of communication systems, and develop analytical methods to help the design and optimization of communication systems with interrupted services. Our work are focused on two systems: optical buffer and wireless sensor network. The common ground of these two problems is they both present the features of service interruption. / Wireless sensor network is an ad hoc network consisting of hundreds of sensor nodes equipped with limited power sources, transmission range and functionality. A simple and effective way to save energy and prolong the network lifetime is to let the nodes interrupt their sensing and data transmission process, enter sleep mode randomly. However, sleep mode corresponds to low power consumption as well as to reduced network capacity, increased latency and slowed system response. We develop a queueing model with server shutting down in a varying neighborhood to model the behavior of sensor nodes, Combining the node queueing model and the network flow balance model, we construct an analytical framework to model the network performance, derive the network capacity, packet delivery delay and node responsive property. We also develop a node power consumption model, which takes the node sleep to active transition frequency into consideration. Our results demonstrate that the sleep/active dynamics produces the predominant impact on the average power consumption and packet delay, and properly choosing the time scale of sleep/active cycle is vital to design a power-efficient sensor network. / Liu Jianming. / "Apr. 2006." / Adviser: Tony Tong Lee. / Source: Dissertation Abstracts International, Volume: 67-11, Section: B, page: 6623. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 109-117). / Electronic reproduction.
