3D print of plasmonic interference patterns

On the occasion of the PhD defense of Dirk Jan Dikken in the Optical Sciences group, these structures were 3D printed in the DesignLab.

The structures represent interference patterns of surface plasmon polaritons that are optically excited through 2 holes in a thin  gold layer on glass.

Thanks to the DesignLab, the in and out of phase interference patterns as measured by Dirk Jan were reproduced on a more human scale; the real size of the interference pattern is about 12*12 um.
