Ion beam sculpting for advanced photonics structures
The interaction of kV energy ion beams at oblique incidence with surfaces creates ripples or periodic patterns due to mass transport.
In this project we are investigating the creation of sawtooth patterns that are then covered with thin film multilayers for structures that resemble blazed diffraction gratings.
