The large-photon-number quantum state is a fundamental but nonresolved request for
practical quantum information applications. We propose an N-photon state generation …

In this paper we describe an upconversion detector in the mid infrared (around 3.5 μm). We
take advantage of the PPLN ridge waveguide technology to achieve single photon detection …

We report on the implementation of a mid-infrared (MIR) interferometer prototype for
furthermore application in the framework of high-resolution imaging in astronomy. This …

In the aim of access the high angular resolution for mid infrared observations, our team
propose to include non linear processes on each arm of an interferometer. This project …

Les interféromètres stellaires sont des dispositifs à très haute résolution angulaire,
permettant une étude approfondie de l'Univers. Cette thèse décrit la mise en place en …
