New Nano-hologram a Boon for 3D in Electronics and Healthcare

A combination of Australian and Chinese researchers has created a new nano-hologram, which is thousand times thinner than human hair, can be seen without 3D goggles, and is easy to develop. If the promises see the day of light, this nano-hologram can revolutionize everyday electronics including smartphones, televisions, and computers, and may also benefit in healthcare diagnostics.

This integration of 3D holography into electronics has been long awaited by the electronic industry, hoping for an ability to display vast amount of data with a 3D pop-up, which cannot fit into two-dimensional electronic devices. Now, this creation of nano-holograms may just pave the way to the future electronics.

Finally, a Hologram that is Smartphone Compatible

According to Min Gu, the leading researchers of the team who has had a distinguished career at RMIT University, conventional computer-generated holograms are too big to be compatible with sleek modern electronic devices. The nano-hologram developed by his pioneering team not only overcomes the size barrier, it can also be fabricated via simple and time-efficient method using laser writing system, which in turn will help the manufacturers in mass production.

Unlike holograms that modulate the phase of light in order to create an illusion of three-dimensional effect, RMIT team has managed to bring the thickness within 25 nanometers via a topological insulator material, which can hold low refractive index in the surface layer as well as ultrahigh refractive index in the bulk. This topological insulator material serves as intrinsic optical resonant cavity, enhancing the phase shifts required for holographic imaging.

Next Stage is to Lay the Film onto a LCD Screen

According to the co-author of the research, the next stage in the development of this nano-hologram is to fabricate a thin film that is rigid enough to be laid onto a LCD screen in order to enable 3D holographic display. This may require the researchers to shrink the pixel size of their nano-hologram by 10 times, but they are hopeful of creating elastic and flexible thin films that can be integrated on various surfaces.
