Member of project 3.2 "Solids and Nanostructures: Electrons, Spins, and Phonons"

Research

The activity of our research group is centered around the direct laser writing of 3d micro-optical systems in solid transparent materials with fs-laser pulses. Our activity is divided in the two topics of (i) Fundamentals of the laser-matter interaction during microprocessing with ultrashort laser pulses and (ii) Direct laser printing of photonic structures with ultrafast laser pulses.

Topic (i) aims at:

  • determining which fundamental mechanisms prevail during plasma formation with ultrashort pulses
  • studying the relaxation processes leading to structural modifications, for instance thermal transients and defect formation.

Topic (ii) deals with the fabrication of functional micro-optical systems, mainly in the bulk of fused silica. The main applications include:

  • Long term data storage
  • Direct part marking under the surface
  • Printing of integrated optical sensors

Curriculum vitae

Since 2015: Principal Investigator on a DFG-funded research project entitled “Micromachining with few-cycle pulses”

2009-: Research associateat the Max-Born Institute, Berlin. Developed, designed and tested advanced optical methods for the characterization of femtosecond-laser induced micro- and nanostructures in the volume of transparent materials: phase-contrast microscopy, quantitative phase-shift interferometry, time-resolved microscopy with random lasers.

2008-2009: Project associateoptics/sensors,Hella Aglaia Mobile Vision GmbH, Berlin. Participated in the development of a front camera for car driver assistance, designed and tested an optical method able to measure the modulation transfer function of the cameras in a production environment.

2007-2008: Research associate,Princeton University, Princeton, NJ, USA. Developed and characterized a new generation of adaptive optics components based on tunable acoustic lenses.
