IET Optoelectronics publishes state of the art research papers in the field of optoelectronics and photonics. The topics that are covered by the journal include optical and optoelectronic materials, nanophotonics, metamaterials and photonic crystals, light sources (e.g. LEDs, lasers and devices for lighting), optical modulation and multiplexing, optical fibres, cables and connectors, optical amplifiers, photodetectors and optical receivers, photonic integrated circuits, photonic systems, optical signal processing and holography and displays.Most of the papers published describe original research from universities and industrial and government laboratories. However correspondence suggesting review papers and tutorials is welcomed, as are suggestions for special issues.IET Optoelectronics covers but is not limited to the following topics:Optical and optoelectronic materialsLight sources, including LEDs, lasers and devices for lightingOptical modulation and multiplexingOptical fibres, cables and connectorsOptical amplifiersPhotodetectors and optical receiversPhotonic integrated circuitsNanophotonics and photonic crystalsOptical signal processingHolographyDisplays
