V. Calvo and N. Pauc at INAC/PHELIQS/ SiNaPS Light sources fully integrated into microelectronics technology are the missing stones of silicon photonics. Silicon, as well as germanium, are not well suited for light emission in their natural form, due to the indirect nature of their bandgap.

We demonstrate the optical trapping of bacteria in a 2D silicon hollow photonic crystal cavity. This structure allows for the Gram-type differentiation of bacteria in a fast, label-free, and non-destructive way.

Researchers at INAC-PHELIQS-NPSC have developed new approaches for the detection of ultraviolet/infrared light using single GaN nanowires. Results have led to the demonstration of the first photodetector-in-a-wire based on intersubband transitions, i.e.

Researchers have succeeded in coupling a semiconductor quantum dot to a vibrating wire. The quantum dot is then able to detect the mechanical vibrations of the wire with very high sensitivity.

Several groups have already reported the fabrication of nanotubes, but such structures exhibit usually poor light emission performances. Indeed, the surface states and defects favor the non-radiative recombination processes that quench light emission.

A new class of optoelectronic devices, such as single-photon sources, is based on semiconductor quantum dots (QDs) embedded in a photonic structure. Nowadays, the best QDs are still obtained via a self-assembly process: these emitters are thus randomly located in the structure.

It has been shown in recent years that mechanical stress can be used to tune the electronic and optical properties of semiconductor quantum dots. For instance, this approach has been implemented to adjust finely the emission wavelength of quantum dot single photon sources.

The Léon Brillouin Great Prize has been founded by the French Optical Society, with the support of the iXCore Research Foundation, to honor the memory of the great physicist Léon Brillouin, whose discoveries have deeply influenced the modern development of Optics.

We have studied the growth and optical properties of AlGaN nanowires, a potential candidate for future ultraviolet light sources. We have evidenced that such structures behave as a collection of quantum dots due to short-scale composition fluctuations.

The distribution of the electromagnetic field is an essential input for the design and development of new photonic structures. The classical near-field microscopy tools (SNOM, PSTM ..) allow to obtain this information experimentally.
