Optics Classification and Indexing Scheme (OCIS)

OCIS provides a flexible, comprehensive classification system for all optical author input and user retrieval needs. OCIS has a two-level hierarchical structure containing 36 main headers and approximately 1100 subcategories. OSA authors, presenters, and reviewers use OCIS to classify and index journal articles, meeting abstracts and presentations, and areas of research interest and expertise.

A PDF version of the OCIS codes is also available. If you have suggestions for changes or additions, please send them to OCIS@osa.org.
