Europe's centre of photonics?

Germany has always been at the forefront of many manufacturing disciplines, and photonics is no exception. Dr Bernd Weidner and Joachim Giesekus explain why

Be it Abbe's theory of microscope image formation, which led to fundamental improved microscopes in 1871, or the Nobel Prize-winning development of laser-based precision spectroscopy by the German physicist Haensch in 2005, the German photonics industry is characterised by a high level of innovation and quality. As a result, Germany can certainly claim to be Europe's leading nation in photonics.

A recent market report shows that the industry is thriving. Spectaris, the German industry association for optical, medical and mechatronical technologies, has recently put together an extensive market report on - among other things - the state of the industry of lasers and optical components in Germany. The world market, which ../includes more than lasers and optical components, is estimated to be worth about e100bn. According to the world market index Optical Technologies, the world market of photonics increased 25 per cent in 2004. This index was established by Spectaris and analyses the revenues of the key players in this industry.

The photonics and precision engineering industry in Germany employs almost 150,000 people and manufacturers predict that this period of growth will continue when the 2005 figures are published. Around 10 per cent of turnover is reinvested in research and development, with around half of that turnover being generated from new products. In the laser and optical components sector (treated separately in this report), total turnover was e4.5bn in 2004, up 12 per cent from the previous year. Exports were up 15 per cent on 2004, and these represented around two-thirds of overall turnover - proving that Germany is a nation supplying photonics products around the world. Around half of these exports were in the EU, with around 15 per cent going to North America. In 2003, Germany increased exports to such an extent that it became a net exporter from a net importer. Asia is also a significant destination. Employment in the sector grew to just over 41,000 employees.

An important factor contributing to this track record is the German government's funding programme, which was established in 2002 and actively supports the development of optical technologies. Between 2002 and 2007, roughly e90m has been pledged by the German Ministry of Education and Research (BMBF) for research in the field of photonics. Before then, the ministry initiated a strategy process in 1999-2000, with the help of industry associations, scientists and industry experts, in order to structure this area of the economy and to promote the use of optical technologies in as many applications as possible. As a result of this, they developed the German agenda 'Optical Technologies for the 21st Century'. The agenda analysed existing application fields, identified new application fields and developed recommendations for policy and industry. In doing so, the agenda provided the basis for the research funding programme which, as a result, is tailored to the needs and requirements of the German industry.

Application fields identified as crucial for the German photonics industry include information and telecommunication, health sector and life sciences, illumination and energy, industrial production, optical sensor technology, and manufacturing of optical components and systems. They include innovative radiation sources, new optical concepts, nano-optics, light and optic measurement, and bio-photonics. 'One can easily see that the application fields themselves can be considered as future technologies, so accelerating the triumphant procession of photonics, which acts as a cross-sectional technology,' says Sven Behrens, CEO of Spectaris.

At European level, the immense significance of photonics and its influence on numerous technologies still has to be manifested. Germany is the driving force in the creation of a European technology platform that aims to enhance the position of optical technologies in the Seventh Research Framework Programme (www.vdi.de/photonics21). It will be founded in December 2005, and is supported by 60 European industry key players and scientists. Starting from the platform 'Photonics21 - Photonics for the 21st century', the needs of the photonics industry can be transported more easily to the European Commission and the European research policy.

To ensure a constant high rate of innovation and high quality of photonics made in Germany in the future, a certain level of education must be guaranteed. Specialised study programmes focus on 'photonics' or 'laser technology'. Several players are working on further improvements in state-of-the-art educational programmes, which meet the needs of the industry. To arouse the interest of younger people, the exhibition 'Fascination Light' gives interesting and accessible insights in the physical background of photonics.

The specific structure of the photonics industry calls for the necessity of a strong network: the industry is comprised mainly of small and medium-sized enterprises, which produce niche products and can be considered as innovation drivers. In Germany, numerous efforts are made to ensure the close contact between industry and research, politics and industry, customers and supplier and between competitors.

In addition to its efforts to promote new technologies, the BMBF's funding programme for optical technologies ../includes specific measures to support networks of competence. The aim of establishing such networks was to create durable structures capable of sustaining an innovation system. The Optical Technology Competence Networks are an ideal platform from which to launch innovation projects, because all the necessary partners from basic research up to the producing industry are members of the networks. At present, nine Optical Technology Competence Networks exist in Germany, which focus their activities in the regions where they are situated. In general, these regions have a strong potential in photonics themselves. The regional focus of their activities means that they are pooling the regional resources and expertise of a wide range of players in industry and science to build up complete value-added chains, to facilitate the development of these advanced technologies. Finally, they strongly support the formation of regional clusters in photonics, which need to be sustained due to the importance of short distances and personal contacts between the players.

The networks closely cooperate with each other and are unified under the roof of OptecNet Deutschland eV (www.optecnet.de/) as the umbrella organisation. The Competence Networks are complementary to the traditional industrial associations, like Spectaris, so that both national and regional aspects of strengthening the optical technologies are recognised.

Another good example is the congress 'Optical Technologies - Chances of Innovation for Germany', which took place in February this year, supported by two German ministries and three industry organisations. Primarily aimed at increasing the awareness of the technology for politicians, it offers a high-level platform for all relevant players, and was attended by more than 300 participants.
