What is the difference between a submission, an abstract, and a summary?

A submission is the record that is created in the online submission system. In order to complete a submission, you must complete the following steps:

  1. Title (The title in the system must match the title on the summary paper that you upload.)
  2. 35-word abstract  (An abstract is a 35-word synopsis of your presentation. If your paper is accepted, the abstract will be printed in the Conference Program.)
  3. Summary (A summary paper is a 2- page document submitted as a PDF, that includes your title, author block, abstract and a summary of your presentation (which may include figures, tables and/or references). This document will be reviewed by the Program Committee. If your paper is accepted, the summary is published in Optics InfoBase.)
  4. Copyright to publish your paper and Permission to Record your talk.
  5. Choose the topics category to which your paper should be submitted. The list can be found under Submit a Paper.
  6. Presentation Preference (Select one of the following: Oral Only, Poster Only or Oral or Poster Acceptable.)
  7. Author Institutions
  8. Author Block (Enter each and every author that is listed on the summary paper.)
  9. OCIS Codes (Please select two; a complete list can be found at www.opticsinfobase.org/submit/ocis.)

Are there guidelines for formatting my summary?

This style guide is a reference for all submitting authors and has remained consistent with past years’ Technical Digest format and style.

Please make sure that your paper does not contain non-English font packages (for example, Japanese, Korean, or Chinese fonts, etc.) in the body of your paper summary, as well as in all figures and tables. Characters in these fonts cannot be seen by reviewers. In the past, we have had particular trouble with MS-PGothic, MS-Gothic and MS-Mincho.

Will I receive a confirmation that my submission was received?

Confirmations will be sent to you when you click on the "Submit" icon once you have finalized your submission.

Will I be notified of acceptance or rejection?

Yes. After the Program Committee has reviewed the submissions and decided which to accept for presentation at the meeting, you will be informed of the decision by email. Only the submitting (contact) author will receive notification.

Help! The deadline is approaching and I have not finished my submission. What should I do?

If the deadline is fast approaching, we suggest that you complete the file upload step last and complete all other required steps first (up to and including the abstract). Beginning a record in Abstract Central is critical; papers for which no record has been started cannot be accepted after the deadline.

Can I submit my paper after the deadline?

Regular submissions cannot be accepted after the deadline. However, you may submit a postdeadline paper to CLEO. Keep in mind that postdeadline presentations should describe new and significant material in rapidly advancing areas. A very limited number of postdeadline submissions will be selected for presentation, and only those papers judged to be truly excellent and compelling in their timeliness will be accepted.

If I need assistance or have a question that is not answered here, who should I contact at CLEO, and how?

You can contact the Technical Papers staff with questions related to submissions either by phone or email: +1.202.416.6191, cstech@osa.org.
