Cleanroom researchers are continuing to advance nanotechnology, and they have recently taken inspiration from a butterfly. This butterfly is called the Callophrys Rubi (or the Green Hairstreak), and has a vibrant bright green color. What gives this color its unique shimmer are 3D nanostructures within the wing.
“This butterfly’s wing contains an immense array of interconnected nano-scale coiled springs that form a unique optical material. We used this concept to develop our photonic crystal device,” said Dr. Mark Turner, graduate of Swinburne University where this research is being conducted.
This technology could be used in developing integrated photonic circuits used in optical communications, computing, sensing and imaging.
