Fractal random cantor superlattices for the infrared

Fractal random Cantor superlattices have been proposed in this paper as wavelength selective and broadband filters. Through the use of genetic algorithm optimization, the authors have demonstrated two examples of broadband filters in the mid-IR with a single, broad stop band from 50 THz to 100 THz. These results prove the concept of broadband fractal random superlattices.
