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
