We start with an general overview of the key principles and technologies of optical code division multiple access (OCDMA) that appeared over almost three decades. We then address our new OCDMA communication technique we referred to as optical fast frequency hopping- (OFFH-) CDMA.

We start with an general overview of the
key principles and technologies of optical code
division multiple access (OCDMA) that appeared over
almost three decades. We then address our new OCDMA
communication technique we referred to as optical
fast frequency hopping- (OFFH-) CDMA.
We define the fundamental principles of the OFFH-
CDMA and propose a set of implementation solutions.
We have found, that multiple Bragg gratings (MBG)
offer the most elegant method to implement the OFFH-
CDMA encoding/decoding functions. Theoretical and
computer simulation analysis have verified and
demonstrated the effectiveness of the new principle.
In addition, we propose new encoding/decoding
architectures that enable a network to accommodate
subscribers with different data rates and
performance levels. We also propose and investigate
a version of the system especially appropriate for
communications in hostile temperature and stability
conditions. Finally, we build an OFFH-CDMA
experimental setup that includes sixteen encoders
and four programmable decoders and demonstrate
successful encoding/decoding operation in various
communications scenarios.
