Introduction

Reasonable and durable exploitation or mineral and energetic resources is one of the main challenge for the future of humanity and of the Earth. Addressing these scientific and society issues requires a global knowledge and understanding of element transfers through geological processes such as magmatism and hydrothermalism at depth and weathering, erosion and sedimentation at the surface. Reaching this goal necessitates a multidisciplinary approach integrating scales from the lithosphere to the mineral. We also believe that in order to make progress on issues related to exploitation of natural resources and their impact on the Environment, at the crossroads between fundamental and applied research, implies the development of a network at the interface between Academia and Industry with researchers having diverse and complementary motivations and expertise.

Missions and research themes

The first aim of FALCoL is to formalize and strengthen a more than ten year long collaborative effort joining Australian and French academic and industrial partners on research projects targeting different stages of the evolution of the lithosphere and of the continental crust from the Archean to the Phanerozoic in order to evaluate the impact of geological processes from the deep Earth to the critical zone (geosphere-hydrosphere-biosphere interface). FALCoL has also the ambition to expand ongoing collaborations between participants to a growing team of partners by structuring a network to stimulate discussions and open new routes for future research on the following topics:

NETWORK ACTIVITIES AND EXPECTED RESULTS

FALCoL is complementary to (i) the LithoSud GDRI (IRD), which corresponds to a North-South network of scientists and dedicated to the formation of the continental lithosphere of the southern hemisphere, (ii) the Labex Ressources 21 held by Université de Lorraine and embracing mineral systems and environmental impacts of mining activities, (iii) the WAXI and SAXI projects funded by a consortium of mining companies with the goal to build a synthesis of geological and geophysical data at the scale of the West African and Guiana cratons, respectively.

The strategy of FALCoL is to offer a space for discussion, valorize existing datasets, support mobility of researchers and students and organize a yearly workshop involving the different partners of FALCoL enlarged to other internationally recognized researchers. During these workshops, the different stages and scales of transfers across the different Earth reservoirs will be treated. Each workshop will be devoted to specific scientific questions and will be fed by reports on different case studies. These discussions will allow to define the state of the art but also to identify debated issues and lead to the elaboration of new projects involving all the facets of mass transfer associated with Earth dynamics.

    Introduction

    “Kia ora koutou katoa”

    The WALL-IN project (confining walls-of-Light in nonlinear Kerr resonators) is an international research action focused on the study of nonlinear dynamics occurring in optical Kerr resonators. This project is managed by Julien Fatome from the Laboratoire Interdisciplinaire Carnot de Bourgogne (ICB) in Dijon (France) in collaboration with the photonics group of The University of Auckland (New-Zealand).

    Research activities

    Optical frequency combs (OFCs) are made of thousands of discrete and evenly spaced frequency lines. They can act as “spectral optical rulers” that enable to measure unknown optical frequencies with extraordinarily high precision and for which its inventors were awarded by the Nobel prize in 2005. Frequency comb systems commercially available mainly rely on bulky ultrashort-pulse lasers and supercontinuum technologies. However, a fundamentally different approach was demonstrated in 2007, when continuous laser light was shown to be transformed into an evenly-spaced comb when confined into a nonlinear Kerr microresonator. It is now well understood that such OFC generation in Kerr resonators is mostly based on the emergence of robust, short and bright temporal structures, called dissipative cavity solitons (CSs). First observed in a macroscale optical fiber ring, CSs have attracted growing interest over the past decade and have led to major advances in numerous fields of science such as massively multiplexed optical telecommunications, optical buffering, lidar systems, astrocombs or spectroscopy for molecular fingerprinting. However, CSs are mostly restricted to optical platforms characterized by anomalous chromatic dispersion, which dramatically limits the range of available spectral bands and thus potential applications. Indeed, recalling that numerous materials are characterized by strong normal dispersion, in particular in the mid-infrared where molecules provide strong absorptions, there is a growing interest in the generation of short temporal structures in normally dispersive Kerr resonators so as to extend the applications of OFCs to new spectral regions. So far, several different strategies have been reported such as dark optical solitons, locking of switching waves, platicons or mode coupling in microresonators. However, generation of broad OFCs in normal dispersion regime is still an opened question. In the framework of the Wall-IN project, we combine the complementary expertise of two leading groups of the nonlinear fiber optics community (ICB laboratory in Dijon and The University of Auckland) to extend the applications of OFCs and associated dissipative temporal structures in normal dispersion Kerr resonators around 1.55 µm. Our strategy is based on the investigation of novel vectorial and multimode nonlinear dynamics in fiber-based macro-resonators which are known to be governed by the same equations than microresonators, whist providing much easier and versatile experimental implementation. Subsequently, our findings will be investigated within micro-fiber loops and finally in integrated Kerr microresonators.

    A fruitful collaboration

    The collaboration between the ICB laboratory and The University of Auckland is focused on the international hot-topic dealing with cavity solitons and optical frequency combs generation in nonlinear Kerr resonators. This collaboration benefits from the complementary and strong expertise of the two groups in nonlinear fiber optics, temporal cavity solitons (UoA) and all-optical polarization control (ICB). In that context, our collaboration has been strongly reinforced by 3 academic stays of J. Fatome at UoA in 2015, 2017 and 2020. This collaborative activity dealing with cavity solitons and optical frequency combs generation has already been awarded by several common scientific contributions.
