A Family of Optimal Multiple-Weight Optical Orthogonal Codes for Fiber-Optic Networks.
Comput Intell Neurosci, 2022 Optical orthogonal codes (OOCs) were designed for multimedia optical CDMA systems with quality of service requirements in optical fiber networks. Two‐dimensional (2‐D) multiple‐weight optical orthogonal codes have been invested as they can overcome the drawbacks of nonlinear effects in large spreading sequences.

In situ method for power re-equalization of wavelength pulses inside of OCDMA codes [PDF]
, 2011 A simple in-situ method to equalize power among individual wavelengths pulses representing two-dimensional wavelength-hopping time-spreading OCDMA code originally generated by a fibre Bragg grating-based OCDMA encoder is presented.

IET Communications, Volume 16, Issue 14, Page 1731-1738, August 2022., 2022 Abstract Traditional optical orthogonal code has small code cardinality, which is vulnerable to the brute‐force attacks by eavesdroppers. In order to improve the anti‐interception performance of optical fibre communication system based on optical coding, a new family of optical code with large code cardinality is proposed.

Investigation and demonstration of all‐optical hybrid fiber‐FSO‐fiber CDMA communication system
IET Communications, Volume 16, Issue 3, Page 246-254, February 2022., 2022 Abstract The authors investigate and demonstrate an all‐optical hybrid fiber‐free space optical (FSO)‐fiber communication system based on optical code division multiple access (OCDMA). Under different turbulence effects, the interception probability and interception distance are used as security metrics, and optimal parameters are obtained when the ...

Constructions of Optimal Optical Orthogonal Codes with Weights Set {5,7} via Cyclic Packing
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 Double‐weight optical orthogonal codes are variable‐weight optical orthogonal codes (OOCs), which have been widely applied in optical networks and systems. Some works have been devoted to optimal (n, W, 1, Q)‐OOCs with max{w : w ∈ W} ≤ 6. So far, there is no explicit construction of optimal (n, W, 1, Q)‐OOCs with W = {5,7}.

Performance survey of classic and Optic network‐on‐chip
IET Circuits, Devices &Systems, Volume 15, Issue 4, Page 393-402, July 2021., 2021 Abstract A system on chip is composed of a large number of intellectual property (IP) blocks on the same silicon. However, as the number of IP blocks on a single chip and their performance continue to increase, a shift from those classic interconnections to optical ones becomes mandatory. This article presents a survey and comparison between an optical
