          Welcome to the Integrated Optics Group at the School of Computing, Universiti Utara Malaysia.  The Integrated Optics Group spearheads research in novel designs for integrated optical devices and lab-on-chip readers for next-generation optical computers.  Future computers use light travelling through optical fiber interconnects to accelerate information transfer.   Intel established the first silicon-based 50Gbps optical data connection link using four 12.5Gbit/s lanes of different wavelength.   IBM later proved that a low-cost monolithic silicon chip could be fabricated commercially in December 2012.  We strive for a balanced deployment of parallel optical interconnects, systems and multimedia applications, information management architecture and optimized operations through artifical intelligence.   We envisage to seamlessly aggregate and interface existing and future computers by bringing together diverse expertise and industry leaders for the generation and commercialization of related industrial applications.    
   
         The Integrated Optics Group is led by Dr. Angela Amphawan.  In her doctoral research at the University of Oxford, she experimentally increased the bandwidth of a multimode fiber by up to 3.4 times by developing the first  holographic selective launch using a binary amplitude spatial light modulator and mathematically analyzed the modal decomposition from the output.  The Optical Technology Research Group currently has about 20 researchers and collaborators.  The slideshow below presents some of the group's current research areas and related papers.
