Rainbow holograms design, optimization and fabrication at KERI

Press Release

International team consisting of specialists from KERI Nanocenter (Miryang, Rep. of Korea), from 3SMK (Seoul, Rep. of Korea), from Interface (Moscow, Russia) and from IMT RAS (Chernogolovka, Russia) were successful in design, optimization and fabrication of high quality rainbow holograms. The rainbow holograms consist of diffraction gratings of variable duty cycle with a minimum stroke size of 50 nm. These gratings cover the whole area of the cylindrical stamp.

They used:

  •  "RainBow" software for hologram design/optimization and lithographic data preparation (Interface, IMT RAS)
  •  NanoMaker controlled SEM based lithography (www.nanomaker.com);
  •  original technology for metal stamp fabrication (cylindrical technology, KERI);
  •  homemade (KERI) original technology for imprinting in plastic media

The technology jointly developed has a set of advantages in comparison:

  •  to common optical (dot-matrix) method as producing holograms of higher quality and
  •  to usage of industrial e-beam lithography systems as much more cost effective tool.

As result Korean parties (KERI NanoCenter and 3SMK) have leased out "RainBow" software and in their part Russian partners performed training to hologram design/optimization and provided support for e-beam lithography.
