    Bookham is a leading manufacturer of optoelectronic components and sub-systems for telecom and industrial applications. Bookham Switzerland AG is a key supplier for high power laser diodes as well as vertical cavity surface emitting laser diodes (VCSEL). The site is located in Zurich and has been formerly known as a part of the IBM Europe research center in Rüschlikon, Switzerland with a long track record in development of breakthrough technologies and high volume manufacturing of laser diodes.
    Markets and applications Bookham Switzerland’s products are serving range from pumping of erbiumdoped amplifiers (EDFA), solid-state and fiber lasers, direct material processing over medical and printing application to motion sensing in computer mice. The site is fully integrated and covers all areas from development over manufacturing to marketing  and sales. From the around 150 people about 40 carry a PhD and approximately 35 people are located in R&D and Engineering.

    Key personal:

    Dr. Norbert Lichtenstein received his PhD degree from the University of Stuttgart in 2002 for his work involving novel high-power red-emitting laser diode types with a main focus on high brightness, wavelength stabilized lasers. Norbert Lichtenstein joined Uniphase Laser Enterprise in 1998 leading Uniphase‘s program for broad area laser device development. At the site in Zurich he held different positions in development and management within JDS Uniphase, Nortel Network as well as Bookham including responsibility for development of 980 nm telecom laser, 1480 nm pump laser and laser diode bars. In his current position as Director R&D he oversees Bookham’s new product development of high power laser diodes for telecom and industrial applications. Mr. Lichtenstein is the author or co-author of more than 35 publications as well as of several patents.

    Dr. Bernd Valk was born 1953 in Siegen, Germany. He studied physics at the University of Bonn, Germany, and received his PhD from the University of Bern, Switzerland, 1985. From 1985 until 1988 he was staff member at TACAN Corp., Carlsbad, USA, where he worked in the field of optically pumped semiconductor lasers and non-linear effects in optical fibers. In 1989 he joined Ascom Tech. He was head of the technology group working in the area of integrated optics and optoelectronic packaging. The focus of the group was on the product development of optoelectronic components based on silicon-micromechanics. In April 1998 he started working for Uniphase Laser Enterprise as a group leader in the area of module packaging. He was responsible for setting up the manufacturing of 980 nm pump laser modules. In his current position as project manager for the packaging activities in Bookham-Zurich he is responsible for the development of various module packages incorporating laser bar assemblies.

    Dr. Martin Krejci received his PhD degree from the Swiss Federal Institute of Technology Zurich (ETHZ) for his thesis "Preparation and Characterization of Heteroepitaxial CuInxSey Layers and Cu(In,Ga)Se2 Substrate Solar Cells". In 1999 he joined Bookham’s site in Zurich when it was part of JDS Uniphase Switzerland as a specialist for materials analysis. Today Mr. Krejci is responsible for the development of Bookham’s industrial laser bar products.


    Role in the project:

    Development of a laser diode array (10cm and 30cm line length) with line focus for the crystallization of a-Si thin films on glass substrates; system integration with optics and certain user interfaces; development of concepts for up-scalability to 1.1m line focus.
