DTU purchases T-Ray 4000 system from Picometrix for terahertz time-domain studies

Advanced Photonix, Inc.® (NYSE Amex: API) today announced that the Lyngby campus of The Technical University of Denmark (DTU) has purchased a T-Ray 4000^® from its wholly-owned subsidiary, Picometrix, for terahertz time-domain studies. Terahertz (THz) science and technology is a key strategic area of development for the Photonics Engineering department of the University. It is the University's plan to integrate THz technology directly into both the undergraduate and graduate students' laboratory curriculum. The T-Ray 4000^® will allow the University to bring experimental demonstrations into the classroom, giving students the ability to participate in live demonstrations of fundamental concepts such as total internal reflection, diffraction, refraction, and waveguide propagation. "The Picometrix system was chosen because of its world-leading specifications, good interface options, low weight, and versatility for the use as a portable system which can be used either in our laboratories, in the class room, and in the environments of external partners", said Professor Peter Uhd Jepsen of DTU Fotonik.

The initial use of the system at DTU is to characterize novel THz photonic bandgap fibers. The flexibility of the system is crucial in measuring critical fiber parameters. The system can be changed easily between transmission, reflection, and collinear or non-collinear measurement configurations. In the future, the university will utilize the system's flexibility to expand into a wider range of applications including imaging and Computed Tomography (CT) scanning. For example, in collaboration with Danish industrial partners, it will be used for fundamental studies of microring resonators and additional nondestructive analysis.

"We are excited to be working with the top researchers at the DTU in continuing to create centers of excellence for THz science and technology. The T-Ray 4000's versatility is validated by API's ability to tap a diverse number of market opportunities that range from research to industrial applications. The T-Ray 4000^® was selected by this active research center above a host of other options due to its superior flexibility and performance capability," said Richard Kurtz, CEO of API.
