Feature Issue of Optics Express

Flat Optics

Submissions Open: 1 September 2023

Submission Deadline: 30 November 2023

Optics Express, welcomes submissions to a feature issue on "Flat Optics" in conjunction with the Flat Optics topical meeting collocated with the Optica Imaging and Applied Optics Congress. Whereas meeting participants are particularly encouraged to submit their work, the flat optics feature issue is open to all contributions in related areas.

Metasurfaces, and more generally flat optics, is a multidisciplinary field that leverages an array of subwavelength features on a substrate, engineered to shape an incoming light beam. They can be designed to perform basic optical functions such as focusing and deflection, as well as perform more complex ones such as polarization imaging, broadband imaging, spatial mode multiplexing and others &emdash;many of which would require a multitude of discrete optical components today. The field encompasses various topics from theory of light interaction with structured surfaces, novel modeling methods, fabrication processes, optical materials, test methods and various applications. The expectation is that this feature issue will further stimulate the field, as well as provide a platform for the participants of the topical to publish their work.

All submissions need to present original, previously unpublished work and will be subject to the normal standards and peer review processes of the journal. The standard Optics Express Article Processing Charges will apply to all published articles. To be eligible for publication, an expanded conference paper needs to add value to the original conference proceedings and the conference paper number must be included in the cover letter at submission. Please see Optica Publishing Group's guidelines on expanded conference papers for details.

Please prepare manuscripts according to the author instructions for submission to Optics Express and submit through our electronic submission system, specifying from the drop-down menu that the manuscript is for the feature issue on Flat Optics.
