The pattern of information written on a Blu-ray disc, regardless of what it is, could lead to better performing solar cells. Researchers at Northwestern University have found that the binary codes of such discs create a quasi-random arrangement of patterns that are nearly optimized for photon management over the solar spectrum.

The Optical Society's Photonics 2014: 12th International Conference on Fiber Optics and Photonics is a biennial event that allows researchers from around the world to showcase a wide range of photonics work, from fiber optics and materials for photonic devices to next generation optical components and devices for optical networks.
Several researchers are scheduled to speak during the event; among them, Philip J. Russell of the Max-Planck Institute who will discuss scientific applications of microstructured optical fiber.
The conference will focus on fiber and guided wave photonics; lasers and nonlinear optics; nanophotonics, plasmonics and metamaterials; quantum optics, information and processing; optical communication and networks; biophotonics; and photonic materials and devices.
