So simple, yet so difficult – towards reliable FIB milling of variable surface topographies

Focused ion beam processing is ideal for the prototyping of high-fidelity 3D components, particularly for quantum applications. However, the actual identification of suitable beam and patterning parameters still relies on personal talent and experience. In my lab, we aim to removing these hurdles by implementing calibration-based and physics-informed pattern generation.

About Katja Höflich

Katja Höflich is head of the Joint Lab for Photonic Quantum Technologies at the Ferdinand-Braun-Institut (FBH) in Berlin, Germany. She received her PhD in natural sciences from Martin Luther University Halle, Germany, in 2011, focusing on the modeling and fabrication of plasmonic nanostructures. Her research interests lie in the design, nanofabrication, and characterization of integrated nano-optical and photonic components for enhanced light–matter interaction. These include chiral plasmonic devices and high-fidelity on-chip components for photonic quantum applications. As an expert in focused ion beam processing, she co-authored the Roadmap for Focused Ion Beam Technologies.
