  • Wider control of the refractive index is desired for new optical applications. Here the authors manipulate block copolymer self-assembled nanopatterns via shrinkage in order to control the refractive index. They achieve an index above 3 over 1,000 nm bandwidth.

  • The refractive index of natural materials only covers a limited range. Here, Chang et al. use the principle of space-filling curves to construct a mesoscopic crystal with a refractive index greater than 1000 at GHz frequencies. The concept is inherently broadband and scalable.
