• Telecoms at 2µm

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
