General Guidelines:

Papers will be reviewed by the experts within the subcommittee (SC) you choose unless they get recategorized by the Program Chairs. To determine which Track (D-, S- or N-) to submit to, please carefully review the descriptions below and keep in mind the focus of each Track as outlined in their Titles. If you are unsure of which SC to choose, please select one that seems the closest. The Program Chairs review all submissions for correct SC categorization and make changes, if required.

The technical program is organized by three tracks: D-, N-, S- and the newly-formed Subcommittee Q (SC-Q).

  • D-Track — In general, this track evaluates papers studying the design, fabrication and characterization of devices, components and fibers. Devices and PICs evaluated in a system should be submitted to the S-Track under the appropriate subcategory.
  • N-Track — Focuses on the networking and service aspects of networks and systems.
  • S-Track — Evaluates papers at the subsystem and system level at the areas outlined in the subcategory titles and the subcategory sub-bullets.
  • SC-Q — Papers related to devices, systems and networks for quantum communications should be submitted to newly formed Subcommittee Q (SC-Q).
