Fourier Transform Spectroscopy (FTS)

Fourier Transform Spectroscopy (FTS)

The Fourier Transform Spectroscopy (FTS) Meeting focuses on the latest advances in instrumentation and applications of FTS to astronomy and astrophysics, atmospheric science and remote sensing, laboratory spectroscopy, analytical chemistry, bio-medicine, and a variety of industrial applications.

Today, Fourier transform spectrometers onboard satellites looking downwards provide new insights on the Earth's atmosphere, climate, and a host of other meteorological and remote sensing applications. Instruments looking out provide a wealth of data targeting galaxies, stars, planets, and many smaller objects within the universe. Ground-based FT interferometers explore a variety of astrophysical and terrestrial fields including the global geographic distribution of CO2 sources and sinks. Chip-scale interferometers fabricated using state-of-the-art nanotechnology open up new opportunities for space and industrial applications. Laser frequency combs dramatically improve the resolution and recording speed of Fourier spectrometers. New spectral regions (e.g., VUV or THz) are under exploration with synchrotron radiation. Ultrashort laser pulses expand the territory of FTS to nonlinear and multidimensional spectroscopy. This international conference will provide a unique opportunity to discuss many of these exciting developments in a strongly interdisciplinary environment.

Industry Panel
Tuesday, 15 November, 17:30 - 19:00
Kongresshalle am Zoo

Renewable energy systems are finally on a global economic rise, exceeding combined new build fossil generation for the first in 2015. Still there is a long way to go, as renewable energies (including hydro) contribute less than a quarter of the worldwide overall energy capacity. In this panel discussion, we will hear different perspectives from politics, research and industry on the status and future of renewable energies and approaches to accelerate market penetration.

The Invention of High Efficient Blue LEDs and Future Lighting
In 1970's and 80’s, an efficient blue and green light-emitting diodes (LED) were the last missing elements for solid-state display and lighting technologies due to the lack of suitable materials. By that time, III-nitride alloys was regarded the least possible candidate due to various "impossible" difficulties. However, a series of unexpected breakthroughs in 1990's totally changed people's view angle. Finally, the first high efficient blue LEDs were invented and commercialized at the same time of 1993. Nowadays, III-nitride-based LEDs have become the most widely used light source in many applications. The LED light bulbs are more than ten times efficient than incandescent bulb, and they last for 50 years!  At their current adoption rates, by 2020, LEDs can reduce the world’s need for electricity by the equivalent of nearly 60 nuclear power plants.

Bio:  Shuji Nakamura is from Ehime, Japan. He obtained his B.E., M.S., and Ph.D. degrees in Electrical Engineering from the Univ. of Tokushima, Japan. He joined Nichia Chemical Industries Ltd. in 1979. He spent a year at the Univ. of Florida as a visiting research associate in 1988, and started the research of blue LEDs using group-III nitride materials the following year. In 1993 and 1995, he developed the first group-III nitride-based blue/green LEDs. He also developed the first group-III nitride-based violet laser diodes (LDs) in 1995. He has received a number of awards, including the MRS Medal Award (1997), the IEEE Jack A. Morton Award, the British Rank Prize (1998) and the Benjamin Franklin Medal Award (2002). He was elected as a member of the US National Academy of Engineering (NAE) in 2003, received the Finnish Millennium Technology Prize in 2006, the Prince of Asturias Award from Spain in 2008, the Harvey Prize of Israel Inst. of Technology in 2010, and the Nobel Prize in Physics in 2014. Since 2000, he is a professor in the Materials Department of the Univ. of California Santa Barbara. He holds more than 200 patents and has published more than 400 papers in this field.

Keynote Speakers
Jérôme Faist, ETH Zurich, Switzerland
Fourier Transform Spectroscopy (FTS)

Quantum-cascade Laser Frequency Combs and Their Application to Dual-comb Spectroscopy   
Quantum cascade lasers have recently demonstrated the capability of operating as optical frequency combs in the mid-infrared and terahertz with high optical power (>100mW). Self-detected dual comb operation and dual-comb spectroscopy were recently demonstrated.
Bio: Jérôme Faist was born in Geneva, and obtained his Bachelor and Ph.D. in Physics, in the group of Prof. F.-K Reinhart from the Swiss Institute of Technology in Lausanne in 1985, 1989 respectively. After a post-doc in IBM Rueschlikon (89-91), he joined F. Capasso's group in Bell Laboratories in 1991 where he worked first as a post-doc and then as a Member of Technical Staff. From 1997 to 2007, he was professor in the physics institute of the University of Neuchâtel. In 2007, he became professor in the institute for quantum electronics of the ETH Zurich.
His central role in the invention and first demonstration of the quantum cascade (QC) laser in 1994 was recognised by the IEE premium (1995), the IEEE/LEOS William Streifer award (1998), the Michael Lunn award (1999), the ISCS "Young scientist award" (1999), and the Swiss National Latsis Prize (2003). His present interests are the development of high performance QC lasers in the Mid and Far-infrared and the physics of coherence in intersubband transitions in the presence of strong magnetic fields.

Pietro Altermatt, Trina Solar Limited, China
Optical Nanostructures and Advanced Materials for Photovoltaics (PV) Optical Properties of Industrially Mass-produced Crystalline Silicon Solar Cells and Prospects for Improvements
The optical properties of mass-produced crystalline Si solar cells are reviewed and the requirements and constraints for their improvements by modern optical methods are outlined from the perspective of one of the largest manufacturers.
Bio: Pietro P. Altermatt’s main area of research has been the development of physical models for the numerical simulation of crystalline silicon solar cells and testing devices. Of equal interest to him is the application of these models to simulation strategies tailored to research, development and mass production. When Pietro worked at UNSW from 1993 until 2002, the UNSW high-efficiency cells were ideally suited for setting up generally valid physical models, because they suffered from very few non-ideal losses. When Pietro set up a modelling group at the Leibniz University Hannover (Germany) in 2005, the models were extended to industrially fabricated solar cells, working in close collaboration with the industry. Now, such simulations form the quantitative basis for improvement strategies in the PV industry, predicting the optimum device design, the necessary production equipment, and the feasible silicon material.

Christian Sattler, German Aerospace Center, Germany
Optics for Solar Energy (SOLAR)

Solar Fuels: Specific Requirements for Solar Concentrator Systems
The production of fuels by concentrated solar radiation is an option for efficient large scale processes. The radiation can either be used to replace fossil fuels for heating established processes like steam or dry reforming of methane. Or at higher temperature to drive thermochemical cycles for water or CO2 splitting into hydrogen, oxygen and CO. Presently most of the technologies are developed with high flux solar simulators. However some scale-up demonstrations on solar towers have been operated. The concentrator systems, mainly heliostat fields, are similar to installations for power production. However the chemical reactions require a different heating regime. Therefore a special optics and control systems have to be developed to achieve the very high temperatures necessary to carry out thermochemical cycles constantly and homogeneously in the whole solar receiver. The presentation will give an overview of the concentrating solar fuel production processes. It will give insight in how to design the required heliostat fields, secondary optics, and control systems.

Bio: Prof. Dr. Christian Sattler is head of the Department of Solar Chemical Engineering of the German Aerospace Center’s Institute of Solar Research. He is also professor for solar fuel production at the Technical University of Dresden. The main area of his work is the production of fuels especially hydrogen by solar thermo- and photochemical processes. He serves as vice president of the research association N.ERGHY a member of the European Joint Technology Initiative for Fuel Cells and Hydrogen and is the national representative to tasks of the IEA’s SolarPACES and Hydrogen Implementing Agreements.
