The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.Optical Materials Express (OMEx), OSA's open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to:Artificially engineered optical structuresBiomaterialsOptical detector materialsOptical storage mediaMaterials for integrated opticsNonlinear optical materialsLaser materialsMetamaterialsNanomaterialsOrganics and polymersSoft materialsIR materialsMaterials for fiber opticsHybrid technologiesMaterials for quantum photonicsOptical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
