Descrizione del progetto
Il carburo di silicio permette di realizzare un pettine di frequenze ad alte prestazioni, ecologico e biocompatibile
I laser sono diventati onnipresenti e, oltre alla luce laser monocromatica, molte applicazioni si basano sulla capacità di produrre contemporaneamente più colori di luce (a frequenze discrete). Gli spettri di queste sorgenti laser assomigliano ad un pettine, da cui il termine «pettine di frequenze». I contributi allo sviluppo della spettroscopia di precisione basata su laser, compresa la tecnica del pettine di frequenze ottiche, sono stati premiati con il Premio Nobel per la Fisica nel 2005. Nella prospettiva del 2020, la riduzione dell’ingombro e dei costi dei pettini di frequenze è fondamentale per ampliare le applicazioni nelle innovazioni odierne. Pettini di frequenze basati su chip che richiedono uno spazio molto ridotto e con un consumo energetico molto basso sono fondamentali. Il progetto SiComb, finanziato dall’UE, intende sottoporre a dimostrazione per la prima volta un pettine di frequenze su chip, compatibile con CMOS e a banda ultra larga, realizzato con carburo di silicio sostenibile e ad alte prestazioni.
Obiettivo
A CMOS compatible and ultra broadband on-chip Silicon Carbide frequency comb (SiComb) is going to be demonstrated for the first time by this project. It is achieved by an interdisciplinary collaboration effort of combing unique optical nonlinearity of SiC, growth of low optical loss SiC thin film and fabrication of high quality factor microresonators. As an enabling technology, the on-chip frequency comb is deemed to have far profound impact on diverse areas of science and engineering, including sensing, timekeeping, distance ranging, searching for exoplanets as well as optical communication. For example, the application of this frequency comb in optical communication as a WDM light source will be demonstrated in this project to show the energy saving and the data traffic handling beyond 100 Tb/s. Compared to frequency combs made from AlGaAs, Lithium Niobate etc, SiC has material sustainability advantages: environmentally friendly, biocompatibility, and extended device lifetime and efficiency, which opens new application potentials. In this ambitious 3-years project, SiComb consortium (7 partners from both academic and industrial sectors) with complementary strengths of SiC material growth, device nanofabrication, nonlinear optics and optical communication systems will collaborate to demonstrate the non-incremental and ground-breaking ultra broadband SiC frequency comb chips, with synergy effect at European level. These results will build leading research and innovation capacity on SiC optical devices and applications across Europe and enhance the competiveness and growth of industrial partners. It will also align with European advancement in frequency comb efforts, as well as innovation competence to position Europe in forefront of technologies in the research and innovation. The future market implementation and utilization is expected to have a strong momentum given by the results and stakeholder establishment in the SiComb project.
