Submit Papers


Submit Postdeadline Paper

Paper Submission Deadline: 3 April, 12:00 EDT (17:00 GMT)

Postdeadline submissions are not an opportunity to submit a paper after the published deadline, but are intended to provide those with late-breaking work an opportunity to submit that work for consideration. Postdeadline submissions should describe new and significant material in rapidly advancing areas. A 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.


The CLEO technical program is composed of 27 topic categories ranging from fundamental science to applications and technology. Questions regarding the paper submission and review process can be directed to the Technical Papers Staff at cstech@osa.org at any time.
