Biomedical optics is a field of increasing importance for a future point-of-care medical analysis. Valuable information about the health status of a person can be extracted by optical means, non-invasive and in a continous mode. In this project, nanoLED light engines based on gallium nitride (GaN) technology available at TU Braunschweig will be developed in order to address novel applications in the field of biomedical sensing.
The Institute of Semiconductor Technology (IHT) operates the Epitaxy Competence Center (ec2), a dedicated research unit for the development of GaN epitaxy and device processing, together with our core partner, OSRAM Opto Semiconductors GmbH, Regensburg, Germany. ec2 offers modern infrastructures for the epitaxy and analysis of GaN based device structures, and in particular 3D nanorods, nanoLEDs and other nanostructures. ec2 also includes processing equipment in order to develop ultra-compact light sources in the visible range, as a basis for light engines for biomedical sensing. The light engines to be developed will be used to demonstrate interesting novel functionality concerning biomedical analysis, measuring optical information on blood and tissue samples.
