And God said, “Let there be light,” and there was light. (Genesis 1:3)



    The science of photonics includes the generation, emission, transmission, modulation, signal processing, switching, amplification, detection and sensing of light. The term photonics thereby emphasizes that photons are neither particles nor waves – they are different in that they have both particle and wave nature. It covers all technical applications of light over the whole spectrum from ultraviolet over the visible to the near-, mid- and far-infrared. Most applications, however, are in the range of the visible and near infrared light. Applications of photonics are ubiquitous. Included are all areas from everyday life to the most advanced science, e.g. light detection, telecommunications, information processing, lighting, metrology, spectroscopy, holography, medicine (surgery, vision correction, endoscopy, health monitoring), military technology, laser material processing, visual art, biophotonics, agriculture, and robotics.

    In the mean time, computer simulations have become a useful part of mathematical modeling of many natural systems in physics (computational physics), astrophysics, chemistry and biology, human systems in economics, psychology, social science, and engineering. Simulations can be used to explore and gain new insights into new technology, and to estimate the performance of systems too complex for analytical solutions.

    By combining these two subjects we can do many simulations or modeling, especially for photonics based application that enhance the science advancement in order to improve the quality of life.

    Applied Laser Spectroscopy

    We have reported in a series of publication the generation of secondary plasma having very low continuous emission background and additional characteristics favorable for spectrochemical analysis. Our further experiments reveal that the shock wave generated by the primary plasma is responsible for the formation of the secondary plasma as well as the excitation of the target atoms. Meanwhile we have also developed its application for in-situ analysis of large metallic surfaces in industry. In our continuing effort to deepen our understanding of the dynamical process of secondary plasma formation as well as to broaden its range of application and improve its practically including its portability, we are currently undertaking the quantitative analysis using high power pulsed laser applied in mining, rocks and fossil analysis, food inspection, biochemical analysis, surgery, etc.

    Compressive of Sensing: When Sensing Meet Compression

    Compressive Sensing is a novel signal acquisition method that offers joint sensing and compression where perfect reconstruction of signal can be made form far fewer samples / measurement than traditional Shannon-Nyquist sampling theorem. Applications and opportunities: (1) New Analog-to-Digital Converter (Analog to Information); (2) One Pixel Camera; (3) Fast Magnetic Resonance Imaging (Fast – MRI); (4) Space Exploration; (5) Optimized Compressive Sensing.

    Computational Intelligence

    Nature-inspired computational methodologies and approaches to address complex problems of the real world applications to which traditional methodologies and approaches are ineffective or infeasible. In Computational Intelligence for Semistructured System we focus on Metabolic pathways, social Network and also with Software Engineering. Some recent research that we report it include Pathways Network between Acid and protein-protein interaction, include with coding and signaling regulatory networks, as well as for robot application.

    Dynamic Simulation Model for Business Decision Making

    Business models systems are characterized by complex structure and dynamic behavior. It’s often difficult to predict or trace the consequences of certain decisions due to the existence of delays, non-linearities and causal feedback inherent to such systems, in other words, the effect of making a decision in one part of the business function can manifest itself in another part of the business system at an unexpected time. There’s a widely held belief that System Dynamics is the only knowledge based way for challenging the increasing complexity of decision making in general and the best solution to avoid unintended consequences.
