IET Optoelectronics publishes cutting-edge research papers in the field of optoelectronics and photonics. The journal covers topics including optical and optoelectronic materials, nanophotonics, metamaterials, photonic crystals, light sources (such as LEDs, lasers, and lighting devices), optical modulation and multiplexing, optical fibers, cables and connectors, optical amplifiers, optoelectronic detectors and receivers, photonic integrated circuits, photonic systems, optical signal processing, as well as holography and displays. Most of the published papers describe original research from universities, industry, and government laboratories. However, we also welcome submissions of review papers, tutorials, and suggestions for special issues. IET Optoelectronics covers, but is not limited to, the following topics: optical and optoelectronic materials, light sources (including LEDs, lasers, and lighting devices), optical modulation and multiplexing, optical fibers, cables and connectors, optical amplifiers, optoelectronic detectors and receivers, photonic integrated circuits, nanophotonics, photonic crystals, optical signal processing, and holography and displays.
