In 2015 we celebrated the International Year of Light, proclaimed by the United Nations to recognize the achievements of light science and its applications, and its contributions to humankind. Advanced Optical Materials has joined in the activities of this special iniciative through publishing a special series of review articles. These “International Year of Light” articles are written by experts in their fields, especially invited for this event. Below you can find all twelve articles of the series.

Plasmonics offers a unique opportunity to break the diffraction limit of light and localize optical signals at nanoscale dimensions. One of the prospective applications of plasmonics is in integrated nanophotonic circuits with high bandwidths. This review summarizes the recent advances in the development of active and passive nanophotonic components based on dielectric-loaded plasmonic waveguides.

Gyroids are chiral minimal surface morphologies which are found in a variety of natural and synthetic systems, ranging from butterfly wing scales to self-assembled block copolymers. The optical properties of gyroid structured materials are reviewed here on two fundamental length scales, which behave as either photonic crystals or optical metamaterials.
