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 pageAppl. 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."

Nature Communications published the experimental realization of dual-comb spectroscopy using quantum cascade laser frequency combs by Gustavo Villares.

We use quantum-cascade-laser frequency combs to demonstrate a high resolution, broadband dual-comb spectrometer.
This article demonstrates the potential of this novel technology. It concludes with the vision of a monolithically integrated mid-infrared dual-comb spectrometer featuring ultra-high sensitivity and selectivity. external pageIRsweep will deliver this technology in an industry ready system.

Dual-comb spectroscopy based on quantum-cascade-laser frequency combs
Gustavo Villares et al., Nature communications 5 Article number: 5192 (2014).

IR-Sweep was created by Andreas Hugi and Markus Geiser

The recent advances in QCL-based frequency combs (external pageA. Hugi et al.) and their application in dual comb spectroscopy (external pageVillares et al.) stimulated the founding of ETH spin-off company external pageIRsweep, where the technology is further pushed towards sensing applications. The co-founders Andreas Hugi and Markus Geiser are also supported by the ETH Pioneer-fellowship program.

Pierre Jouy et al. are on the cover of "Analyst"

April 2014. Pierre Jouy et al. were offered to make the cover of the 7th May edition of "Analyst" for their contribution to the use of Mid-infrared quantum cascade lasers for liquid and gas spectroscopy. They platform enabled the detection of CO2 isotopes ratio down to 0.02% and a solution of cocaine down to 10ug/mL filtered using a microfluidic system. This work is a collaboration with EMPA, EPFL, Haute Ecole ARC Ingénierie, UNINE and Hochschule für technik FHNW for the IRSens project (external pageNano-Tera and external pageSNF).

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.

Distinguished invited speakers will present achievements and future perspectives for devices and their applications. See http://www.20yearsqcl.ethz.ch for more information.

Textbook on Quantum Cascade Lasers by Jerome Faist published

The ISBN-13 is: 978-0198528241. It covers a wide range from fundamentals to applications and mid-infrared QCLs as well as THz QCLs.

Nature publishes Faist group article on Mid-Infrared Frequency combs using QCLs

13.12.2012. The recent realisation of an elecrically pumped mid-infrared frequency comb using a quantum cascade laser in the Faist group is published in Nature today. The full article is available external pagehere. This work is very relevant for spectroscopy as many small characteistic vibrational-rotational resonances of small molecules are found in this frequency range.
