Research ArticleOpen accessIn the keywordsION-IMPLANTED GLASS WAVEGUIDES: A REVIEWShu Cheng, Bo Peng, Hai-Tao Guo et al.As a well-known technique for material modification, ion implantation has become an effective method to fabricate waveguide in optical glasses. The guiding structures can be accurately controlled by the adjustment of the species, energies and fluences of the implanted ions. In the present work, we review the results of up-to-date research on the fabrication, characterization and applications of the ion-implanted … …Physics International, Vol. 4, Issue 1 · 20 May 2013 · 13,460 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Thermooptic Polymer Switch Based on Directional Coupler StructureAbu Sahmah Mohd Supa’at, Mohd. Haniff Ibrahim, Abu Bakar Mohammad et al.A novel thermooptic (TO) polymer switch based on directional coupler structure is proposed for the first time. The key element of the proposed switch is a buried square core polymer waveguides which has been designed for optimum mode matching and coupling with the single mode optical fiber configuration and have large effective index difference by the thermooptic effects. At a … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,374 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect 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 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Analysis of In-Band Crosstalk, Out-of-Band Crosstalk and GVD-Based Power Penalties in DWDM and TDM/DWDM-PONSIbrahim Mohamed, Mohammad Syuhaimi Ab-RahmanIn addition to the ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, the consequent upgrade from the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to Next-Generation Optical Access Networks (NG-OANs) has become inevitable. Different architectures for creating a NG-OAN have been proposed in the literature. Among those architectures, … …Journal of Computer Science, Vol. 11, Issue 3 · 13 May 2015 · 7,317 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Doping Position on the Active Silicon-on-Insulator Micro-Ring Resonator Based on Free Carrier InjectionB. Mardiana, Sahbuddin Shaari, P. Susthitha Menon et al.Problem statement: Metal interconnects have become significant limitation on the scaling of CMOS technologies in electronics integrated circuit. Silicon photonics has offers great potential to overcome this critical bottleneck due to the advantages of optical interconnects. Silicon-based optical micro-ring resonator is promising basic element of future electronic-photonic integrated circuits because of its wide applications on photonic devices such as modulator, … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 9 Aug 2012 · 7,342 accessesView PDFCite
