Journal of Optics publishes new experimental and theoretical research across all areas of pure and applied optics, both modern and classical. Research areas are categorised as:Nanophotonics and plasmonicsMetamaterials and structured photonic materialsQuantum photonicsBiophotonicsLight-matter interactionsNonlinear and ultrafast opticsPropagation, diffraction and scatteringOptical communicationIntegrated opticsPhotovoltaics and energy harvestingWe discourage incremental advances, purely numerical simulations without any validation, or research without a strong optics advance, e.g. computer algorithms applied to optical and imaging processes, equipment designs or material fabrication.
