1 Photonic Research Group The Photonic Research group in Engineering, led by Associate Professor Dr Faisal Rafiq Mahamd Adikan, was established in early The group’s initial target was to explore the field on integrated photonics based on glass technology and polymer substrates. To this end, a combination of selective area spray doping and single beam direct UV writing was adopted in making chips containing both optically active and passive functions. The group’s collaboration with the Optoelectronics Research Centre (Southampton) was aimed at producing small form factor distributed Bragg reflected lasers and amplifiers. The group runs the Flat Fibre Laboratory – an optical fibre drawing facility for conventional optical fibres, photonic crystal fibre, and Flat Fibre fabrication. In addition, our sister lab in the Department of Physics hosts a Flame Hydrolysis Deposition system, a mask aligner, DC sputter, ICP etcher, surface profiler, and prism coupler. The Faculty of Engineering has a central facility for FE-SEM and XRD analysis. The group’s optical characterisation lab include broadband sources, waveguide characterisation apparatus, microscopes, polishing jig, optical spectrum analysers (UV, IR, and Far-IR) for biosensor development. Simulation tools include COMSOL Multiphysics and MATLAB. The group also runs a single beam direct UV writing set up. Contact us: We are looking for researchers! Postgraduates, Postdocs, Academics Research Facilities A major achievement by the group took place early 2010 when it was granted University of Malaya’s High Impact Research grant to begin work on the hybrid optical fibre-glass chip called Flat Fibre. The grant allowed for the setting up of a single-sided optical drawing tower – currently the only one in a South East Asian university. Following the commissioning of the optical draw tower facility end of 2010, the group became a focal point in photonic research, forming collaboration with a number of Malaysian universities and research institutions. In addition, it has also embarked on a 5-year Ministry of Higher Education High Impact project on the development of Photonic Biosensors, focusing on rapid detection of the dengue virus. Furthermore, the group has began initial efforts in fabricating multistructured optical fibres, mainly geared towards sensing applications.

2 Research Topics Integrated Optics, Fibre Fabrication and Sensors Solution Doping of Planar Glass Waveguide. This research aims to incorporate rare-earth or bismuth into silica-on- silicon samples for applications involving lasers and amplifiers. The work involves a doping process that can be performed over pre- determined areas – termed selective area doping. The ultimate objective is to fabricate a chip containing both optically passive and active devices on a single optical material platform. Direct UV Writing of Novel Waveguide Devices. This work utilises single-beam direct UV writing technique in fabricating novel structures such as tapered waveguides. The facility can produce waveguides on photosensitive samples (germanium doped glass) and ‘soft’ materials such as polymers via ablation or cross-linking. An extension of the work involves the use of a dual beam set up that allows for fabrication of Bragg gratings (a collaboration with the Optoelectronics Research Centre : Prof. Peter GR Smith’s group). Photonic Crystal Fibres. The group is exploring this exciting field, involving the design, fabrication and characterisation of PCFs to be applied mainly in sensing applications. Fabrication of hollow core fibres has been successfully demonstrated recently and the aim is to investigate non- linear properties for use in biosensing. Novel Flat Fibres. This new and patented technology combines the advantages offered by the optical fibre and planar format. The research is aimed at creating fully flexible glass optical chips, and novel photonic crystal structures within the cross section of the Flat Fibre samples. These samples will find applications in distributed multi-point sensing, data transport, and fibre based lighting. Bragg-based Sensors. These projects are applied research in nature. The group addresses niche, local issues requiring optical based sensors, particularly Bragg- based ones. These include leak detection, refractive index sensing, structural monitoring, and pollution detection. Sustainability and green technology would be the general theme of this work. Photonic Biosensors. The work is aimed at using photonic approaches in sensing the presence of infectious disease carriers such as the dengue virus. The group is currently employing several techniques including long period gratings, surface plasmon resonance, and thinned cladding Braggs.
