2015 has been designated the International Year of Light and Light-based Technologies by UNESCO. This global initiative aims to highlight the importance of light in our everyday lives and how it has contributed to the development of society. To celebrate this yearlong event, the editors of the Physical Review journals have organized a collection of papers that represent important breakthroughs in the field of optics, from fundamental insights into how light behaves, to findings that were critical in the development of everyday technologies. These papers will be free to read throughout 2015.
