A Fiber Optics Displacement Sensor (FODS) Imaging System For Laboratory Experiments In Photonics Devices And Systems

The aim of this work is to educate and train students on the development of a simple intensity modulated FODS as a quantitative technique for the imaging and estimation of surface roughness. This non-destructive imaging tool uses inexpensive and readily available equipments, hence suitable for employment in the teaching module of Photonics Devices and Systems.

An Optical Trapping Based Microfiber Sensor For Biomedical Applications

The evanescent-wave trapping and propulsion of microscopic spherical particles via the fabrication of microfibers using a simple and low-cost flame brushing technique. The focus will be on the investigation of the polystyrene microspheres manipulation using the evanescent optical field surrounding a silica microfiber via the proposed optical trapping mechanism. This mechanism can be used to manipulate and identify minute biological objects such as bacteria, yeast and organelles.

Optical Network Monitoring for Tree-structured Passive Optical Network using
Residual Power of Amplified Spontaneous Emission

An optical monitoring system for point-to-multipoint (P2MP) network using the residual power of an erbium doped fiber amplifier (EDFA) is developed. EDFA is used to amplify the downstram signals and in the meantime,its residual power is used as the monitoring source. Thus, no additional monitoring source is required and this will decrease the cost of the monitoring system. Instead of monitoring, the system is also capable to locate the exact fault of the fiber automatically.

Graphic User Interface (GUI) Design of Engineering Subjects for Interactive Learning

An educational software is developed using MATLAB-GUI. Students are able to understand the subject matter more efficiently as user is able to obtain the answer automatically. With interactive learning materials, for instance, the visualizations of the wave propagating in different materials can also be simulated. Thus, this will enhance the understanding of the subject and will attract the students in studying engineering subjects.  The standalone of the program is also developed such that user does not need to install Matlab in order to use the system.
