Research ArticleOpen accessIn the author namesAnalysis of Jitter Impact on High Speed Transmissions of Wavelength-Division Multiplexing NetworksHazura Haroon, Hanim Abdul Razak, Sahbudin Shaari, P. Susthitha MenonIn this study, we conduct a thorough assessment of the effect of jitter occurrence in high speed 10 Gbps and 200 GHz Wavelength-Division Multiplexing (WDM) optical network. First, we present a simulation model to study the effect of jitter presence in the proposed network and then determine the maximum amount of jitter which the network can withstand. The model is … …American Journal of Applied Sciences, Vol. 11, Issue 12 · 13 Jan 2015 · 6,679 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEffect of Low Temperature on the Fabrication of Microring Resonator by Wet EtchingHazura Haroon, Sahbudin Shaari, P. Susthitha Menon et al.Research related to semiconductor devices often relies on wafer fabrication. The fabrication of Silicon (Si) based devices by anisotropic wet etching can be affected by many etching parameters such as etching temperature, crystal orientation and percent of composition. Most of the anisotropic wet etchings by KOH solution done before were conducted at temperature over 70°C. We found that the temperatures … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 7 Nov 2012 · 7,131 accessesView PDF Cite

Research ArticleOpen accessIn the author namesOptical Code-Division Multiple-Access and Wavelength Division Multiplexing: Hybrid Scheme ReviewHesham A. Bakarman, P. Susthitha Menon, Isaac A.M. Ashour, Sahbudin ShaariProblem statement: Hybrid Optical Code-Division Multiple-Access (OCDMA) and Wavelength-Division Multiplexing (WDM) have flourished as successful schemes for expanding the transmission capacity as well as enhancing the security for OCDMA. However, a comprehensive review related to this hybrid system are lacking currently. Approach: The purpose of this paper is to review the literature on OCDMA-WDM overlay systems, including our hybrid approach … …Journal of Computer Science, Vol. 8, Issue 10 · 29 Aug 2012 · 7,864 accessesView PDF Cite

Research ArticleOpen accessIn the author namesNanocrystalline Zn0.9Mn0.1S Thin Film: Case StudiesMohammad Syuhaimi Ab-Rahman, Noor Azie Azura Mohd Arif, Abang Anuar Ehsan, Sahbudin ShaariProblem statement: The high quality of ZnS:Mn nanocrystals is important in nanotechnology industries. The perfect chemical procedure is significant to produce the best of nanocrystals. Hence, this research is concern on the good chemical method in processing manganese doped zinc sulphide nanocrystals. Approach: For the first step, Mn doped ZnS nanocrystals were synthesized by using sol gel spin coating method. … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 8,124 accessesView PDF Cite

Research ArticleOpen accessIn the author namesLow-Cost Encoding Device for Optical Code Division Multiple Access SystemMohammad Syuhaimi Ab-Rahman, Boonchuan Ng, Norshilawati Mohamad Ibrahim, Sahbudin ShaariProblem statement: Instead of using Fiber Bragg Grating (FBG) to develop the coded spectrums, which consist of expensive elements, the grating also are highly sensitive to environmental changes and this will contribute to the increment of capital and operational expenditures (CAPEX and OPEX). Approach: This study presented the development of low-cost 16-ports encoding device for Optical Code Division Multiple Access … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,644 accessesView PDF Cite
