SAFIR: Solitons, lAsers, Fibers and InfraRed photonics

The SAFIR team, attached to the Photonics department, is based on a very strong coupling between non-linear system theoreticians and experimental researchers in non-linear optics. It aims to develop new advanced optical functions that take advantage of the properties of light in different environments. The objective is to bring together our most recent advances in non-linear optics, ultra-fast optics, optoelectronics, optomechanics and innovative photonic materials in order to develop original approaches to optical signal processing that are disruptive with respect to the state of the art. This team is managed by Bertrand Kibler et Frédéric Smektala.

The main fields of investigation are high-speed all-optical information processing, new laser sources, nonlinear optics with coherent or incoherent waves, strongly nonlinear optical fibers for the infrared. Such works are mainly based on fundamental studies dedicated to original nonlinear phenomena in the field of optical fibers and waveguides. A part of our activities also answers the needs expressed by manufacturers, some of whom are involved in contracts (Bertin Technologies, CEA Valduc, URGO, TEB, Resolution Spectra Systems, etc.). Our ambition is to assert our position as a center of excellence at the national and international level in the field of nonlinear optics in optical fibers and to strengthen our industrial relations in the field of laser applications.

Research Activities

Our projects aim at (i) developing fiber-based high-repetition-rate pulse sources, novel all-optical functions for signal processing (e.g., self-organization of light and polarization control), and the generation of wideband IR light (supercontinuum) sources, (ii) studying fundamental nonlinear wave structures and their collective interactions such as solitons, breathers, and dissipative solitons, as well as the study of extreme events (rogue waves) in optics and their links with hydrodynamics.

Our activity on laser instrumentation focuses on the development of specific unconventional sources for industrial prototypes of strategic importance. The experience gained in the field of portable LIBS (Laser Induced Plasma Spectroscopy) analysis is extended to the field of geology.

Our research activities are also increasingly opening towards the mid-infrared (2-20 µm) because many molecules of application interest in chemistry, biology, medicine and the environment have a signature in this spectral domain. In particular, we are developing a new generation of optical fibers made of transparent chalcogenide and tellurite glasses in this spectral range. On the other hand, we develop and use optical frequency combs for applications intended for telecommunications and spectroscopy (health, environment).

Finally, the production of nano-optical devices integrated on a substrate connected to optical fibers and compatible with silicon technology is a major objective.

One of the team’s objectives is to balance fundamental and applied researches in the field of photonics and to promote know-how transfer in industry. While continuing to develop projects supported by national and European programs, the team also wishes to focus on projects carried out directly in partnership with companies or with high development potential.

Le projet  ERC PETAL (Polarization condEnsation for Telecom AppLications) porté par Julien Fatome, propose une approche radicalement différente du contrôle de la polarisation de la lumière dans les fibres optiques. Il s’agit d’une rupture technologique vis-à-vis des systèmes actuels de contrôle de la polarisation basés essentiellement sur des systèmes opto-électroniques à boucle de rétro-contrôle. L’idée novatrice développée dans PETAL est d’explorer et d’exploiter une propriété originale de la lumière à auto-organiser son état de polarisation dans une fibre optique. Un des objectifs du programme PETAL sera également de généraliser cet effet à d’autres paramètres de la lumière, notamment dans le domaine spatial à l’aide de fibres optiques supportant plusieurs modes de propagation. L’enjeu sociétal du projet PETAL sera d’intégrer ce type de fonctions optiques dans les futurs réseaux de télécommunications de sorte à migrer progressivement vers des réseaux optiques de plus en plus transparents et intelligents.

Modulation instability is a phenomenon of common occurrence in various fields of physics such as hydrodynamics, plasma physics and nonlinear optics, and was investigated from the 1960s onwards. This nonlinear process is known as a general precursor of highly localized wave structures, called breather waves, through amplification of perturbations.

Recent experimental configurations based on nonlinear fiber optics have allowed to evidence new breather structures and interactions such as rogue breathers, superregular breathers, breather molecules, and some dark-wave counterparts.

The Non Linear Glasses and Special Optical Fibers Group @ ICB Lab in Dijon is among international leaders for studying nonlinear effects in special optical fibers based on nonlinear infrared glasses such as chalcogenide or tellurite fibers, for mid infrared supercontinuum generation for example.

The Non Linear Glasses and Special Optical Fibers Group owns a strong expertise in the fabrication of non-silica optical fibers and all the facilities to synthesis soft glasses and preforms as well as to draw fibers. The Group owns skills to manufacture high quality optical glasses combining infrared transparency and high non-linear optical properties. For example, tellurite glasses cast in the laboratory are transparent up to 6 μm and have non-linear refractive indices 30 times greater than that of silica. Chalcogenide glasses can be transparent up to 10 to 20 µm depending on their chemical composition with nonlinear indices 100 to 1000 times greater than that of silica glass. The group has mastery of the mechanical machining of these glasses to obtain preforms adapted to the drawing of microstructured optical fibers. A versatile drawing tower dedicated to the drawing of all types of low-melting glasses is available in the group to draw optical fibers with distinct refractive index profiles: step-index fibers with varying core diameter or microstructured fibers such as suspended core fibers for example. By this way, a fine control of the chromatic dispersion is achievable, and also of the nonlinear properties such as supercontinuum generation in the infrared. Recently, the Group has demonstrated a supercontinuum generation spanning from 2 to 14 µm in a GeSeTe step index fiber [A. Lemière et al., JOSA
B 36 (2) A183 (2019)].

Dispersion and non-linearity are two effects widely considered to be harmful to the quality of an optical pulse. Nevertheless, when understood and controlled, these two effects open up a large range of possibilities. By exploiting these effects in optical fibres or waveguides, we are working to implement fundamental building blocks for ultra-fast information processing. Thus, we are working on the generation and the emporal or spectral manipulation of atypical optical profiles and on the optical functions of future networks. To achieve optimal performance, we can implement linear shaping steps, concepts from time-space duality or algorithms based on neural networks.

Nowadays, the communication traffic is inexorably increasing and the growing fiber-to-the-home (FTTH) deployment as well as the demand of high definition video content will not stop this trend. Unfortunately, it seems that we are reaching soon a ‘capacity crunch’. To prevent it, radical approaches have to be adopted. The two best candidates are the space division multiplexing and the emergence of a new spectral band. The favorite band is around 2 µm thanks to the large amplification band of Thulium. It is likely that the interest for the 2 µm wavelength band increases because it seems to be the perfect candidate for the convergence of fibers, photonics and plasmonics.

We are currently working on telecommunications at 2 µm. We explore the transmission of high bit-rate signal into subwavelength waveguides. Several material are considered as TiO2SiGeSi or SiN. First demonstrations have been recently published (see links). An (Open Access) interview is avalaible here.
