APL Photonics

APL Photonics Publishing fundamental and applied photonics research across multiple disciplines

The name APL Photonics is about values and community. “APL” stands for the values we share with our parent (Applied Physics Letters) and sister (APL Materials) journals - promoting significant advances and novel understandings in our fields through research reports that are driven forward by peer-review. As a new, open access journal for the photonics community, APL Photonics expands on these valu

es and is the home for fundamental and applied multidisciplinary research anchored in photonics, and the platform for next-generation innovations in the field. In response to the diverse community and its communication needs the Journal features Articles, Letters, and Special content – specifically Invited Articles, Perspectives, Tutorials and Special Topic sections. – see the guide for authors for details on the different article types: https://publishing.aip.org/authors/journal-guidelines. Covered topics include:

Light sources
Nonlinear optics
Optoelectronics
Nanophotonics
Plasmonics
Biophotonics and biomedical optics
Ultrafast photonics
Optical communications
Quantum photonics
Optical imaging
Photovoltaics
Guided wave optics
Sensors
Terahertz

Manuscripts that focus on mathematical and computational problems only marginally related to photonics are not suitable for publication in APL Photonics. Similarly, papers focused on incremental technical advances, engineering applications, or materials science are outside the journal’s scope.
