Metal infiltration in transparent substrates

In collaboration with the laboratory of Prof. Andreas Mortensen (LMM), we investigate the combination of metal infiltration processes and femtosecond laser exposure and etching to create three dimensional micro-scale metal structures free or embedded in a transparent substrate.

Laser morphing process

Manufacturing object with nanometer resolution and yet with overall features sizes of hundreds of microns or more is extremely difficult and requires new approaches.

Here, we investigate how this can be done by transforming a shape into another one. While this idea has been used for creating disc resonators or for melting optical fiber-tips into lenses for instance using CO2 lasers, here, we explore how this concept can be expanded to more complex shapes and eventually generalized.

Sub-micron laser structuring

The structuring of materials down to sub-micron resolution has multiple applications, non-only for information storage but also for shaping light in general.
