The Journal of Quantum Electronics comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems, and applications, must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics
