Research
The Optical Nanomaterial Group (ONG) focus on material investigations at the nanoscale (1 nanometer being 1/1'000'000'000 of a meter). The ONG laboratory develops high resolution imaging tools to study the photonic properties of unusual structures. Indeed, this field is dominated by metals and semiconductors for their reliable optoelectronic properties. In contrast, the ONG team investigates a new family of nanocrystals, the metal-oxides, with more functionalities. We develops top-down and bottom-up fabricated nanostructures with metal-oxides, mainly lithium niobate and barium titanate. One of our main goal is to find strategies to control and enhance the optical nonlinearities of materials at small scale to obtain versatile compact photonics devices.
