Giacomo Scalari (*1972), Senior Research Scientist at the Institute for Quantum Electronics, is interested in the terahertz (THz) portion of the electromagnetic spectrum. THz builds a bridge between optics and electronics and acts a gate to sensing applications and spectroscopy. Scalari’s research addresses “frequency combs”, which act as rulers in the frequency domain and can measure the frequency of electromagnetic radiation – including light – very precisely. Scalari will use his ERC Consolidator Grant to create on-chip, self-referenced frequency combs operating in the THz spectral range, where there is currently no compact comb source available. These devices will be appealing for metrology and material inspection, non-invasive imaging for medical applications, and wireless communication.
