This master thesis is dedicated to the design of a thermal infrared, single-mode fibre-fed spectrograph associated with a ground-based nulling interferometer. This is done in the framework of SCIFY, a European Research Council (ERC) Consolidator project lead by Denis Defrère and dedicated to the spectroscopy of exoplanets. The configuration is chosen to be entirely reflective as an alternative to the grism design. The instrument operates in the L band (3.5 - 4 µm) in which water and methane have strong signatures, and aims to achieve a resolution power of R=2000. The different considerations related to ground-based spectroscopy are presented. Several methods to reduce off-axis aberration are also investigated. The spectrograph is analysed with ray-tracing software (CODE-V) and optimised to meet the scientific requirements. Ce mémoire est consacré à la conception d'un spectrographe en infrarouge thermique à alimentation par des fibres optiques monomodes et associé à un interféromètre de type nulling au sol. Ceci est réalisé dans le cadre de SCIFY, un projet financé par le Conseil européen de la recherche (CER), dirigé par Denis Defrère et consacré à la spectroscopie des exoplanètes. Une configuration réflective est analysée afin de proposer une alternative au design possédant un grism. L'instrument opère dans la bande L (3.5 - 4 µm) dans laquelle l'eau et le méthane ont de fortes signatures spectrales, et vise à atteindre un pouvoir de résolution de R=2000. Les différentes considérations liées à la spectroscopie au sol sont présentées. Plusieurs méthodes pour réduire l'aberration hors axe sont égalements étudiées. Le spectrograph est analysé à l'aide d'un logiciel de ray-tracing (CODE-V) et optimisé pour répondre aux exigences scientifiques.

Submarine fiber optic cables are critical communications infrastructure for States around the world. They are laid on the seabed, are often no bigger than a garden hose, and transmit immense amounts of data across oceans. These cables are the backbone of the internet and phone services and underpin core State interests, such as the finance sector, shipping, commerce and banking industries. Without the capacity to transmit and receive data via submarine cables, the economic security of States would be severely compromised. Despite the fact that 95 per cent of all data and telecommunications between States are transmitted via submarine cables, there is little understanding of how these cables operate. As a result some States have developed policies and laws that undermine the integrity of international telecommunications systems. Submarine Cables: The Handbook of Law and Policy provides a one-stop-shop of essential information relating to the international governance of submarine cables. The Handbook is a unique collaboration between international lawyers and experts from the submarine cable industry. It provides a practical insight into the law and policy issues that affect the protection of submarine cables, as well as the laying, maintenance and operation of such cables. In addition, the law and policy issues in relation to other special purpose cables, such as power cables, marine scientific research cables, military cables, and offshore energy cables, are also addressed.
