Call for Papers:
Optical Code Division Multiple
Alan Willner, University of Southern
Janet Jackel, Telcordia
Submission Deadline: 1 November 2006
Optical code division multiple access (OCDMA) is a technique in which
each network user is assigned a unique code rather than a specific wavelength or
time slot. This approach allows the same available bandwidth to be shared among
the various users, and the code assignments can be flexibly and dynamically
changed. CDMA is, of course, quite valuable in wireless systems and had been
explored in the optical domain since the mid 1980s. Recently, OCDMA has received
increased attention because of significant advances in the enabling
technologies, optimal coding schemes, and efficient network algorithms.
Due to the increase in interest and the number of published articles
in OCDMA, it was felt that the time was ripe for a special issue in the
Journal of Optical Networking
) on the topic. The research community has demonstrated advances in
synchronous and asynchronous systems, based variously on manipulation of phase,
frequency, time, and wavelength.
A critical question remains as to the ultimate utility of OCDMA, as
opposed to or in addition to time and wavelength multiplexing approaches.
Applications have been proposed, ranging from PONs for FTTX to the use of codes
for flexible networking and for augmented security.
This special issue focuses on the technology of OCDMA and on its
applications, including its use in networks, possible coexistence with other
types of communications, and issues relating to the control and management of
networks that incorporate OCDMA.
Scope of Submission We welcome submissions on topics including, but not
- Novel coding concepts, algorithms, and constructions
- Synchronous and asynchronous implementations
- OCDMA-enabled network architectures, topologies, and protocols
- Enabling hardware
- Demonstrations of OCDMA

- Comparison and coexistence of OCDMA with other multiuser schemes
Manuscript Submission To submit to this special issue, follow the
normal procedure for submission to JON, indicating ``OCDMA' in the ``Comments'
field of the online submission form. For all other questions relating to this
feature issue, please send an e-mail to email@example.com, subject line ``OCDMA.'
