ERC consolidator grant for Giacomo Scalari
Giacomo 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. Giacomo is one of three recipients of an ERC consolidator grant at ETH.
ETH medal for Gustavo Villares
Congratulations to Gustavo Villares, who received the ETH medal for this Ph.D. thesis on QCL combs for spectroscopy applications. The medal is awarded by the rector of ETH for outstanding theses.
Recent work on THz QCL combs highlighted in Nature Photonics
The recent Faist group publication external page Appl. Phys Lett. 108, 171104 (2016) got highlighted by Nature Photonics: "Now, Markus Rösch and colleagues from ETH Zurich have developed an on-chip THz dual-comb set-up that does not require a fast detector. Two THz QCLs were processed next to each other by dry-etching techniques on the same chip and connected individually to two current sources."
Electronics Weekly highlights our collaborative work on graphene THz modulators
"The fastest electro-optic THz switch yet has emerged from free electron laser research at the University of Exeter. Graphene, meta-material and plasmonics-based; the exotic device can modulate a THz beam to 60% depth at 40MHz."

Jérôme Faist receives an ERC Advanced Grant
23.10.2013. The European Research Council had to choose the best from no less than 2,400 projects. Happily, the winning researchers, who receive an ERC Advanced Grant, include five from ETH Zurich and Jérôme Faist is among them. In his project, he wants to develop new quantum structures using micro and nano-production technology. It involves a kind of chimera of quantum mechanics: a structure that moves like photons, but interacts like electrons. Faist wants to investigate how abrupt changes in boundary conditions can make ‘virtual photons’ into ‘real photons’, which display behaviour that has not been possible to explain so far. The project aims to enable quantum-optical experiments in the terahertz spectral range and to predict and investigate advanced states of graphene.
