Ivan Favero, CNRS senior researcher at the MPQ laboratory, has just been awarded an ERC Proof of Concept grant. The project, entitled TUPHO (TUning of PHOtonic resonators) aims to improve the reproducibility of micro and nanophotonic devices, which remains an important technological barrier. To this end, the project explores a new technique that allows to reduce the errors at the end of the fabrication process, in a permanent way and at low cost. The objective is to tune the photonic resonators with an accuracy of 0.01%, or even to make them indistinguishable when necessary. This is made possible by a process recently discovered and patented in the laboratory. More details can be found on the INP website.
