Resumen
Optical switches and wavelength converters are recognized as two of the most important DWDM system components in future all-optical networks. Optical switches perform the key functions of flexible routing, reconfigurable optical cross-connect (OXC), network protection and restoration, etc. in optical networks. Wavelength Converters are used to shift one incoming wavelength to another outgoing wavelength when this needs to be done. Always residing in optical switches, they can effectively alleviate the blocking probability and help solve contention happening at the output port of switches. The deployment of wavelength converters within optical switches provides robust routing, switching and network management in optical layer, which is critical to the emerging all-optical Internet. However, the high cost of wavelength converters at current stage of manufacturing technology has to be taken into consideration when we design node architectures for an optical network. Our research explores the efficiency of wavelength converters in a long-haul optical network at different degrees of traffic load by running a simulation. Then, we propose a new cost-effective way to optimally design wavelength-convertible switch so as to achieve higher network performance while still keeping the total network cost down. Meanwhile, the routing and wavelength assignment (RWA) algorithm used in the research is designed to be a generic one for both large-scale and small-scale traffic. Removing the constraint on the traffic load makes the RWA more adaptive and robust. When this new RWA works in conjunction with a newly introduced concept of wavelength-convertible switches, we shall explore the impact of large-scale traffic on the role of wavelength converter so as to determine the method towards optimal use of wavelength convertible switches for all-optical networks.

Resumen
In this paper, we investigate the three-stage, wavelength–space–wavelength switching fabric architecture for nodes in elastic optical networks. In general, this switching fabric has r input and output switches with wavelength-converting capabilities and one center-stage space switch that does not change the spectrum used by a connection. This architecture is most commonly denoted by the WSW1 (r, n, k) switching network. We focus on this switching fabric serving simultaneous connection routing. Such routing takes place mostly in synchronous packet networks, where packets for switching arrive at the inputs of a switching network at the same time. Until now, only switching fabrics with up to three inputs and outputs have been extensively investigated. Routing in switching fabrics of greater capacity is estimated based on routing in switches with two or three inputs and outputs. We now improve the results for the switching fabrics with four inputs and outputs and use these results to estimate routing in the switching fabric with an arbitrary number of inputs and outputs. We propose six routing algorithms based on matrix decomposition for simultaneous connection routing. For the proposed routing algorithms, we derive criteria under which they always succeed. The proposed routing algorithms allow the construction of nonblocking switching fabrics with a lower number of wavelength converters and the reduction of the overall switching fabric cost.

Resumen
Esta tesis constituye un estudio detallado y exhaustivo de las propiedades de una variedad específica de ondas ópticas solitarias. Observadas experimentalmente por primera vez en 1995, estas ondas estan formadas por un haz óptico a frecuencia fundamental y su segundo armónico que están ligados entre sí y viajan juntos en el material cuadrático; y son debidas al equilibrio entre la difracción lineal que sufre el haz al propagarse y un término no lineal de segundo orden en la susceptibilidad del medio. Las llamamos por eso solitones ópticos en medios cuadráticos o simplemente 'solitones cuadráticos'. También se les conoce como 'Solitones Multicolor' aludiendo al hecho de que requieren de haces a diferentes frecuencias para formarse.
Un medio no-lineal cuadrático tiene por fuerza que ser no-centrosimétrico, lo cual es una variedad de anisotropía. Una gran parte de los materiales no-lineales cuadráticos (los que tienen mayor interés para la industria) son uniaxiales lo que significa que presentan un eje de simetría que suele llamarse eje óptico. De la dirección de un haz relativa a ese eje óptico dependen las características de la propagación del haz en el medio cuadrático no-lineal. Una consecuencia de eso en configuraciones de interés es un desvío ('walk-off') sufrido por el haz respecto a su dirección de propagación inicial al entrar en el material no-lineal.
Las propiedades de los solitones cuadráticos 'caminantes' son también estudiadas en la tesis, estableciendo que existe una relación entre la potencia inyectada en el medio y el ángulo de desvío (walking angle).
Una parte importante de la tesis está dedicada al estudio a través de exhaustivos experimentos numéricos del potencial de estas ondas solitarias para constituir la base de dispositivos de conmutación y encaminamiento totalmente ópticos que puedan hacer realidad la promesa de la red transparente totalmente óptica. Los experimentos han permitido identificar varias configuraciones de interés con niveles de potencia y dimensiones que permiten plantearse el diseño y construcción de dispositivos comerciales de conmutación y encaminamiento totalmente ópticos basados en solitones ópticos cuadráticos.
This thesis is a comprehensive study of the fundamental properties of a specific kind of optical spatial solitary waves. First observed experimentally in 1995, these solitary waves are formed by an optical beam at a fundamental frequency and its second harmonic which propagate together and are mutually entangled; and are due to a balanced interplay between the beams' linear diffraction and a second-order nonlinear susceptibility of the medium. They are thereby referred as 'Optical Solitons in Quadratic Nonlinear Media' or simply 'Quadratic Solitons', They are also known as 'Multicolor Solitons' recalling that they are formed by beams at different frequencies.
A quadratic nonlinear media needs to be non centrosymmetric which is a special kind of anisotropy. A great deal of quadratic nonlinear materials (the most used by industry such as lithim niobate, KTP, etc.) are uniaxial meaning that they feature a symmetry axis known as 'optical axis'. The direction of propagation of an optical beam relative to that axis determines the characteristics of the beam's propagation through the quadratic nonlinear material. A main result of that in some configurations of interest is a walk-off suffered by the beam as it enters the quadratic material.
The properties of the families of quadratic solitons in the presence of a linear walk-off (quadratic walking solitons) are studied as well in the thesis stating that there is a relationship between the power injected into the medium and the walking angle, suitable to applications of all-optical switching and routing.
An important last part of the thesis is devoted to the study from a practical viewpoint and through extensive numerical experiments of the potential of these solitary waves as the basis of practical all-optical switches and routers which could take the all-optical transparent network to a reality. The experiments have allowed to identify several configurations of interest with power level and dimensions suited to practical applications which could allow the production of commercial all-optical switching and routing devices based on quadratic solitons.

Resumen
Todays supercomputers employ the fastest processors incorporating the latest VLSI technology. Unfortunately, usable system performance is often limited by excessive interprocessor latency. To overcome this bottleneck, this thesis explores the use of all-optical path interconnection networks using a new topology defined by Coke Reed [31]. This work overcomes limitations of previous optical networks through a novel use of defection routing to minimize latency and allow more processors to collaborate on the same application and dataset. In this thesis research, the data vortex is formally characterized and tested for performance. Extra angles serve as virtual buffers to provide required system performance, even under asymmetric mode operation. The data vortex is compared to two well-known interconnection networks (omega and butterfly) using metrics of average latency and message acceptance rate. The data vortex is shown to outperform the comparison networks, with a 20-50% higher acceptance rate and comparable average latency. The impact of angle size is also studied, and a new, synchronous mode of operation is proposed where additional angles are added to increase the virtual buffering of the network. The tradeoff between virtual buffering and angle resolution backpressure is explored, and an optimal point is found at the 1:6 I/O to non-I/O (virtual buffering) angle ratio. The new mode and optimal angle count are used to form data vortex networks that perform as well as larger networks with fewer total nodes. Finally, hierarchical layering with data vortex clusters is proposed and compared to a single-level data vortex. In todays technology, similar performance is attained at high network communication locality loads (> 2/3), and a 19% latency reduction is obtained at the highest locality loads (> 95%) for current optical switching technology. For projected future technology, the clustered system is shown to yield up to a 55% reduction in latency for applications with 2/3 or better locality.

Resumen
All-optical packet switched networks with flexibility and capability to deal with the bursty traffic is one solution to deal with the ever increasing demand for bandwidth. To fully utilise the potential of such networks and to ensure that high-speed packets, passed through a number of nodes, are faithfully delivered to their intended destination with minimum delay times, packet header processing and routing decision needs to be carried out in the optical domain not in the electrical domain. This is to avoid the speed bottleneck imposed by the slow response of currently available electronic devices beyond 40 Gb/s. At present, packet header recognition is carried out by sequentially correlating the incoming packet header address with every entry of a local routing table. For a small size network, with a reasonable size routing table, sequential correlation is viable both in terms of processing speed and implementation complexity. However, for a large size network with a very large size routing table of hundreds or thousands of entries, the cost, complexity and processing time does become a real issue. The latter will lead to a noticeable increase in the packet processing time at every router, which could be significantly reduced by a non- conventional signal formatting. In this thesis, an all-optical 3-input AND gate and an all-optical 1 x2 switch with high contrast ratio are proposed as an essential element in all-optical routers. New routing schemes employing pulse position modulation (PPM) packet header format as well as single and multiple PPM based routing tables (PPRTs) are proposed and investigated. The main advantage of the proposed scheme is reduced size routing table leading to a faster router processing time compared to the routers with conventional routing tables (CRTs). The correlation-time gains offered by the proposed schemes are given by theoretical calculations. For optical packets with 4-bit binary address, all-optical 1x3 routers employing single and multiple PPRTs with an entry slot of 6.25 ps offer — 100 and — 400 times faster processing times when compared to the routers employing CRT, respectively. The performance of the proposed routers employing single and multiple PPRTs are assessed in terms of optical signal-to-noise ratio (OSNR) in multi-hop routing by means of numerical simulations and theoretical analysis. It is shown that predicted and simulated OSNR decreases by —2 dB after each hop. New packet header address formats proposed offers reduced complexity of nodes by employing single or multiple PPM based routing tables. Adopting a hybrid header address format, it is shown that routers with multiple PPRTs can operate at 160 Gb/s with the output intra-channel crosstalk of -18 dB and with output packet power fluctuation of 2 dB. Finally, a WDM router employing a single PPRT, capable of processing packets at different wavelengths simultaneously, is proposed and its inter-channel crosstalk performance is investigated. At 160 Gb/s, results obtained show an inter-channel crosstalk of — -27 dB at a channel spacing of greater than 0.4 THz and a demultiplexer bandwidth of 500 GHz.

Resumen
This thesis investigates optical interconnection networks for high performance switching and routing. Two main topics are studied. The first topic regards the use of silicon microring resonators for short reach optical interconnects. Photonic technologies can help to overcome the intrinsic limitations of electronics when used in interconnects, short-distance transmissions and switching operations. This thesis considers the peculiarasymmetric losses of microring resonators since they pose unprecedented challenges for the design of the architecture and for the routing algorithms. It presents new interconnection architectures, proposes modifications on classical routing algorithms and achieves a better performance in terms of fabric complexity and scalability with respect to the state of the art. Subsequently, this thesis considers wavelength dimension capabilities of microring resonators in which wavelength reuse (i.e. crosstalk accumulation) presents impairments on the system performance. To this aim, it presents different crosstalk reduction techniques, a feasibility analysis for the design of microring resonators and a novel wavelength-agile routing matrix. The second topic regards flexible resource allocation with adaptable infrastructure for elastic optical networks. In particular, it focus on Architecture on Demand (AoD), whereby optical node architectures can be reconfigured on the fly according to traffic requirements. This thesis includes results on the first flexible-grid optical spectrum networking field trial, carried out in a collaboration with University of Essex. Finally, it addresses several challenges that present the novel concept AoD by means of modeling and simulation. This thesis proposes an algorithm to perform automatic architecture synthesis, reports AoD scalability and power consumption results working under the proposed synthesis algorithm. Such results validate AoD as a flexible node concept that provides power efficiency and high switching capacity.

Resumen
Recent advances in device technologies have opened new opportunities for implementing OTDM in very high-speed long-haul transmission as well as networking. The multi-terahertz bandwidth made available with the advent of optical fibers has spurred investigation and development of transparent all-optical networks that may overcome the bandwidth bottlenecks caused by electro-optic conversion. In future fiber-optic broad-band integrated digital services networks, the large data rates in the fiber-optic transmission links as well as the large number of packets transmitted per second will place sever demands on the required transmission bandwidth and reconfiguration speed of packet switches. Although electronic switching technology has already achieved high switching speeds, it is quite possible that it will be difficult for electronic switches to match the transmission bandwidth that the fiber-optic link can provide. In today fiber-optic packet-switched networks, routing of the packets is made with opto-electronic LiNbO3 crossbar switches. Switching speed of these devices is practically limited only up to several tens of GHz.

Resumen
Non-linear interference filters (NLIF) incorporating ZnSe spacers were first shown to exhibit optical bistability in 1984 [1,2]. Since then they have been successfully used in a number of digital optical circuit demonstrations [3]. Although these devices, which rely on a thermally induced nonlinearity, have limited low-power switch speeds (0.1 µs-100 µs) they have a very high transmission bandwidth, up to several THz, and can therefore act as an all-optical relay. They are therefore excellent candidates for spatial switching, or signal routing applications. A single NLIF may be configured as a 2 × 2 spatial switch by using both reflection and transmission outputs, as shown in fig. 1. An array of such devices may be used to form a non-blocking switch network or crossbar switch [4].

Resumen
A Generalized Exclusive-OR (GEO) module is a boolean and connectivity complete logical representation of soliton dragging logic gates [1,2]. All-Optical designs using GEO-modules can lead to minimal component implementation of many important functions because the GEO-module logic is closely tied to the physics of the fiber gates. We use two or three GEO-modules to design NOR-gates, routing switches, and two versions of a time slot interchanger.

Resumen
Intelligent society demands diverse communication services such as the telephone, facsimile and the high definition TV. To improve flexibility and efficiency of the transmission system under these diverse demands, Asynchronous Transfer Mode will be installed as a new standard method. In this mode, information is divided into many cells of a constant bit-length with headers. Each cell chooses its own route by itself, depending on address information in its header. To realize ATM network for massive demands in future, optical communication technology will be applied. For this, an all-optical self-routing switch, which changes signal route by address information on optical signal itself, is strongly required. Figure 1 shows our approach to realize this switch. That is a Mach-Zehnder interferometer with nonlinear optical medium inserted into one arm. An address light, whose wavelength is slightly different from that of a signal light, controls the phase status of the interferometer through the refractive nonlinearity. Therefore, it also controls which output-port a signal cell passes through.

Resumen
A self-routing optical switch using ring topology is proposed. This switch self-routes multiple optical packets simultaneously to their destination ports. The incoming and outgoing data streams are serial, but all internal transfers are parallel. It can easily adapt to changing service, traffic and control requirements and effectively exploit new optical components without changing the basic switch architectures. The switch can be used for central office switching or for remote unit switching.
