dual-Wavelength Erbium Fiber Laser in a Simple Ring Cavity
Research Output | Dar Al-hikmah Library | IIUM Only

By controlling the cavity loss of the modes using a variable optical attenuator, specific intensities of distributed modes can be fed back into the erbiumdoped fiber to produce signals without mode competition, thus resulting in stable lasing as a means to overcome mode competition in a homogenous gain medium. Two lasing signals were obtained with

Dual Wavelength Fibre Laser with Tunable Channel Spacing Using an Soa and Dual Awgs
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we propose and demonstrate a dual wavelength fibre laser (DWFL) based on the use of an inhomogeneously-broadened semiconductor optical amplifier (SOA) gain medium as well as two arrayed waveguide gratings (AWGs) together with two optical channel selectors (OCSs) and a broadband fibre Bragg grating (FBG) to generate dual wavelength ou

Preparation of Porous Alumina for Biomedical Applications Through Protein foaming-Consolidation Method
Research Output | Dar Al-hikmah Library | IIUM Only

The present work reports a novel method for preparation of porous alumina using egg yolk both as consolidator and foaming agent. Suspensions with an alumina to yolk ratio of 1 in weight were prepared by stirring for 3 h and the resulting slip was poured into cylindrical shaped moulds followed by foaming and consolidation by drying at temperatures o

Singapura ialah sebuah negara pulau kecil di Asia Tenggara. Keluasan tanah negara itu sebelum tahun 1960-an tidak lebih daripada 581.5 kilometer persegi. Oleh sebab bilangan penduduk yang meningkat selain usaha pembangunan yang rancak, Singapura memerlukan kawasan tanah yang lebih luas. Salah satu jalan meluaskan kawasan adalah dengan kerja penamba
