Scientific Background

I am a physicist who graduated from the University of Augsburg. My main fields of research revolve around solid state physics, material sciences and more specifically nanostructures. As a concrete example, I investigated the optical properties of (Al)GaAs nanowires using surface acoustic waves (SAW) to modulate their electronic band structure for my Master thesis.

Current Research Topic

I am investigating (Al)GaAs integrated photonic circuits that are tuned by SAWs. By using the properties of SAWs I achieve fast, dynamic and contactless modulation of light signals.


The project goal aims at improving current information technology by inventing faster, smaller and more efficient photonic circuit components.
