Full textThis thesis falls within the scope of high-speed short-reach optical communication where the growing need in data transfer forces the current architectures to evolve as quickly. Acces network and data-center components and subsystems must follow this growth, especially on the photoreceiver side. 40 Gb{s and beyond high-speed communications are limited by the current photoreceiver architecture, which, due to the integration of both of its main functions (photodetection[PD]/amplification[TIA]), limits the maximum achievable bandwitdh. In order to reduce the amount of components and price caused by multi-architectures, photoreceivers bandwidth must be increased. Two solutions are proposed so that the photoreceiver performances can be optimized : A co-packaging approach in which both main functions of the photoreceiver are considered as black boxes to which must be added an external circuit allowing to increase the bandwidth, and a co-design approach in which a new transimpedance amplifier (TIA) is designed, integrating a pre-equalizing function based on the photodiode characteristics, allowing an enhancement of the photoreceiver bandwitdh

Full textThe interaction between technological, economic, strategic and organisational and regulatory innovation has induced a high level of dynamism in the Telecommunications industry. Its evolution can be characterised by two phases: a phase of modernisation with the emergence of a model of competitive operator, followed by a phase of convergence and increased globalisation. In this context, we analyse the technological and managerial dynamics in the Telecommunications industry around two dimensions. The first is the deploying and re-configuration of relational assets enhancing competitiveness and innovation. Such relational assets allow establishing and moving positions in a context of increasing competition and convergence. The second deals with the process of internationalisation of the industry, with the internationalisation of operators, the globalisation of technologies and standards, and the technological catching-up in emerging economies

Full textThis thesis analyses the impact of telecommunications on firms' productivity and organisation. The study is articulated around two research topics: one is mainly interested in micro-economic aspects (the theory of production and firms' organisation), while the second analyses a subject closer to macro-economic modelling (the technological progress). The thesis is composed by three principal papers: the first defines the starting point of my theoretical reflection, i. E. The modelling of the externalities of networks in the function of production; the second article analyses the relation between use of technologies of communication and firms' hierarchical organisation; finally, the third article studies the impact of telecommunications on total factor productivity and technical progress. These three papers are introduced by a review of the literature, describing the existing models on the principal topics we analyse. This review of the literature is organised in two parts. The first part focuses mainly on the competition models on firms offering goods likely to present the network externality effect; i. E. The additional value that a new subscriber brings to the community of the already existing subscribers. The second part analyses the literature on technological progress, and the most recent models on telecommunications infrastructure and growth. Two econometric works, one on telecommunications demand by firms, and the other on telecommunications and French national growth, are also presented as an illustration of the problems analysed, respectively, by the first and the second part of the thesis. Our thesis shows that the impact of telecommunications on the economy can be better analysed and measured at the micro-economic level than at the macro-economic level. The analysis of this missing link; is an interesting subject for further research

Full textOur research expands the theoretical framework for regulatory policy analysis of recent reforms in network industries with high technological dynamics, the telecommunications sector in particular. The specific nature of this sector's infrastructure and demand implies prevalence of market failures such as price collusion and underinvestment. Technology adoption, asymmetric information, market access control and regional coordination on regulation are some of the main topics discussed in this dissertation. Economic regulation by market mechanisms appears as the appropriate way of handling natural oligopolies, scale and scope economies, high entry costs and network externalities. In the first part of this work we have examined the theoretical arguments on which regulatory authorities base their functioning. In the second part we propose some mathematical models representing firm's behaviour and organization in a network economy context. Choices on price and investment are thus explained as strategic reactions to market and regulatory incentives. Some empirical tests have been done to get a better understanding of links between telecoms investment and economic development in different parts of the world. Finally, we have also performed studies on regional cooperation on regulation and on the potential effects of new technologies on society as a whole

Full textTechnological substitution is the process by which disruptive technologies replace the dominant ones in an industry. Such paradigmatic shifts have a great effect on the strategic planning of a firm’s technology portfolio. The time-path of the fractional rate of substitution is most often perceived as a smooth S-shape pattern. However, substitution is not a passive unified phenomenon. I review nine empirical examples of more complex substitution patterns which I identified and that are not properly replicated by current models of technological change. Hence, the overarching aim of this research is to understand the broad underlying dynamics of technological substitutions. The formulation of classical models of substitution imposes simplification constraints to reach analytical solvability. I use the system dynamics simulation methodology to build upon existing models by integrating many dynamic aspects derived from a broad theoretical framework and to explore the links between social dynamics, technological developments and substitution patterns. A very interesting pattern of “double shift” was found whereby the substitution of technology n+1 for technology n is suddenly interrupted by the emergence of a third technology n+2. Understanding the underlying dynamics of a double shift could allow a firm to follow a bold strategy of technological leapfrogging

Full textAt the beginning of this millennium, the technical convergence is about to born. Nevertheless, how this opportunity can be transformed into innovative services by a multidivisional group, competing within the telecommunication industry. More precisely, how can we develop strategies of innovation, whose implementation requires the cooperation between the divisions of the group? This research, conducted within France Telecom, leads to two main results: Cooperation between divisions to generate new offers is multiform: It involves different kinds of divisions (product divisions, R&D division and distribution divisions), different resources. It raises different assets and is limited by different brakes. The multidivisional structure of the group limits the implementation of some strategies of innovation. This limit can be broken thanks to the coordination between the top management, middle managers from the R&D division and the distribution divisions and staff members from the distribution divisions. The role of these three different actors differs from the nature of the strategy of innovation: autonomous or deliberate. This thesis concludes that the development of strategies of innovation within multidivisional groups, whose structure is similar to France Telecom's one, can be achieved if the relation between R&D and distribution divisions and products divisions changes
