Recent Progresses in Optical Code-Division Multiple-Access (OCDMA) Technology
View Published Articles →01About This Special Issue
The recent growth of broadband access services and the need for high speed and large capacity access networks have driven the development of Optical code-division multiple-access (OCDMA) for next-generation broadband access networks. OCDMA is a promising technology for addressing the bandwidth and flexibility demands of local area and access networks. Statistical multiplexing, service differentiation, asynchronous operation, flexible allocation of channels, fairness, and enhanced data privacy are some of the attractive advantages of OCDMA that make it a current forefront topic of research. This special issue focuses on the OCDMA technology and its applications. Potential topics include, but are not limited to:1. New OCDMA coding sequences and constructions.
2. New design of OCDMA detection techniques.
3. OCDMA-enabled network architectures and topologies.
4. Analysis of OCDMA system performance improvements.
5. OCDMA applications and its core technologies.
6. Key issues affecting the use of OCDMA for privacy.
7. Comparison of OCDMA with other optical-based multiple-access technologies.

IP Routing by Phase Induced Intensity Noise Suppression in Optical CDMA Network
Issue: Volume 4, Issue 2-1, March 2015Pages: 18-21Received: 4 November 2014Accepted: 10 January 2015Published: 11 February 2015Abstract: In this paper, we explore avenues to efficiently use spectral amplitude coding optical code-division multiple-access (SAC-OCDMA) technique as a solution to the Internet protocol (IP) routing bottleneck in the global internet access. This work reveals for the first time the authors proposed a novel class of codes called the flexible cross correlatio... Show More -
A Review of Ultra-Short Soliton Pulse Generation Using InGaAsP/InP Microring Resonator (MRR) Systems
Issue: Volume 4, Issue 2-1, March 2015Pages: 6-17Received: 8 December 2014Accepted: 11 December 2014Published: 27 December 2014Abstract: System of microring resonators (MRRs) incorporating with an add/drop MRR system are presented to generate single and multi-temporal and spatial ultra-short soliton pulses applicable in optical soliton communications. The chaotic signals caused by the nonlinear condition could be generated and propagated within the system. The Kerr effect in the MRR... Show More -
Issue: Volume 4, Issue 2-1, March 2015Pages: 1-5Received: 8 November 2014Accepted: 12 November 2014Published: 22 November 2014Abstract: In this paper, we propose a system of microring resonator (MRR). This system uses a laser diode input which can be incorporated with an optical add/drop filter system. When light from the laser diode feedbacks to the fiber ring resonator, the pulses in the form of soliton can be generated by using appropriate fiber ring resonator parameters and als... Show More
