Dr. Kamal Hammani was born in 1985.
He received the PhD degree at the University of Burgundy in 2011. Then He went as a post-doctoral research fellow at the Optoelectronics Research Center (University of Southampton) in United-Kingdom (2012-2013).
Since September 2013, he is an Assistant professor at the University of Burgundy.
His Research (at ICB UMR 6303 CNRS/uB) covers nonlinear optics, optical communication, optical fibers, nanophotonics and plasmonics for applications in opto-electronics in near- and mid- infrared.
More precisely, our research activities are mainly based on integrated waveguides.
Our aim is to develop a new platform based on Titanium dioxide (as a nonlinear material) for supercontinuum generation and the related applications.
Research activities
Telecoms at 2 µm
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 TiO2, SiGe, Si or SiN. First demonstrations have been recently published (see links). An (Open Access) interview is avalaible here.
Titanium Dioxide and new emerging materials
The emergence of 2 µm band will never replace the existing telecommunications bands. Therefore, we are interested in an alternative platform that could be make bridges between all bands from the interconnects band at 850 nm to standard telecommunication band at 1.55 µm passing through the band at 1.310 µm. This is why we focus our attention on the titanium dioxide that is transparent from the visible to the Mid-infrared with negligible two-photon absorption. This platform will be benchmarked by comparison with already used platform (SOI, Silicon nitride, silicon Germanium).
The titanium dioxide (TiO2) is a low cost material compared to III-V semiconductors. It handles high power intensities and is non-toxic compared to chalcogenide glasses. It is transparent from the visible to the mid-infrared wavelength of interest in our project. Regarding the nonlinearity, we can expect at least 30 times better than silica . Moreover, it presents no TPA at standard telecommunications wavelength. This is why we believe that the titanium dioxide represents the perfect candidate for the next generation of telecommunication and all-optical processing.
We have recently shown that the ease of fabrication allows new kind of grating couplers. We have also demonstrated for the first time an octave-spanning supercontinuum generation in such waveguides
Hybrid Plasmonics
The ohmic losses are lower at higher wavelength (2µm) in such a way that surface plasmon polariton (SPP) has longer propagation length. This length stays too low to expect efficient nonlinear effect required for nonlinear all-optical processing. This is why we work on hybrid waveguides that could take advantage of SPP confinement features.
More specifically, we are interested in CMOS plasmonics and in the use of colloidal quantum dots (in the visible).
Dual-Comb Spectroscopy
We are mainly interested in eletroc-optically generated combs at 2 µm and more recently on the conversion towards Mid-IR
Projects
ANR Project n° ANR-21-CE24-0010-01 (https://anrelectrode.wixsite.com/english/about)
ELECTRODE proposes to explore such highly nonlinear and dispersion engineered hybrid waveguides based mainly on two alternative materials, namely silicon-rich nitride and titanium dioxide. For the first time, this project considers thoroughly the titanium dioxide as an alternative platform for nonlinear integrated devices and particularly in the context of multi-octave supercontinuum generation.
Unfortunately, as in the case of optical fibers, it is necessary to specifically design a waveguide for a targeted application. Once manufactured, it is, in principle, difficult to adapt the dispersive properties. ELECTRODE will investigate, for the first time, the possibility of reconfiguring dispersive properties post-fabrication thanks to the thermo-optical properties of the considered materials.
This project will explore the limits of knowledge by focusing on modulated width waveguides also called dispersion oscillating waveguides. This project, which contains a large numerical part as well as advanced fabrication aspects and proof of principle, is also intended to be applied.
Solution 2.0 proposes a set of functions or devices based on nonlinearity or on thermo-optic effect working in any telecommunications band. For the first time, this project considers thoroughly the 2 µm waveband in the context of integrated devices for telecommunications and introduces a new photonic material almost unexplored in such a context: the titanium dioxide (TiO2).
This project is supported by the French “Investissements d’Avenir” program, project ISITE-BFC (contract ANR-15-IDEX-0003).
