Addressing and control of optical nanosources by integrated or fibered plasmonics
2015
Surface plasmon polariton (SPP) can confine light on subwavelength dimensions. Since they are not diffraction limited, they are of great interest for addressing and controlling optical nanosources. For example, a metal nanowire defines 1D plasmonic waveguide with a great potential for either addressing or coupling quantum emitters. Therefore, SPP opens great opportunities for integrated optical applications. However, SPP suffer from ohmic losses that jeopardize the applications of plasmonic components. In this context, we study the possibilities provided by an hybrid plasmonic-photonicstructure to couple efficiently an emitter to a fiber mode. Such a structure paves the way for fibered sing…

The ‘Biovigilance Flore’ national weed survey gathers about 5400 field data over 714 communes and 9 years. At this spatial and temporal scale, it is possible to partition the impact of different factors on weed flora and to highlight differences between generalist species and species more specialized to particular environmental or agricultural conditions. In this article, we analyzed and compared changes in weed flora of both oilseed rape and winter wheat. Results showed that a part of changes observed in winter wheat can be attributed to new species ‘entering’ or increasing their frequencies in oilseed rape. On one hand, this results stress the importance of considering the crop rotation s…
Topology of beginning : Heidegger’s interpretation of Anaximander
2022
In this thesis, the main work is to initiate a series of discussions based on Heidegger’s interpretation of Anaximander. Our work is articulated around two main axes: first, we situate his interpretation of Anaximander in the progression of Heideggerian thought, and by comparing his interpretations of Anaximander at three different periods, we attempt to clarify the thread of Heidegger’s interpretation of Anaximander. In this axis devoted to his specific and detailed interpretation of Anaximander, we try to place the interpretation of Anaximander in the theoretical framework of the “topology of presence” in order to examine the evolution and development of Heidegger’s thought. Secondly, we …
