MVP has several processors in it, and its operation is characteristic of parallelism and pipeline; therefore, real-time signal processing can be done on it. This paper presents the image processing system based on MVP, explains the principles of parallel task assignment and hardware pipeline design, and gives out the example of target tracking and edge detection.展开更多

The system exhibits dual-mode PIT effects in the visible and near-infrared regions. By adjusting the geometrical parameters of the structure, we can manipulate not only each single PIT window, but also the double PIT windows simulta- neously. Our structures may have potential applications for optical communication, integrated optics, and optical information processing. The finite element method （FEM） illustrates our theoretical design.展开更多

In this paper, linear and S-shaped MIM waveguides are cascaded together to design the model of Mach-Zehnder interferometer （MZI）. Nonlinear material has been used for switching of light across its output ports. The structures of even and odd parity generators are projected by cascading the MZIs. Parity generator and checker circuit are used for error correction and detection in an optical communication system. Study and analysis of proposed designs are carried out by using the MATLAB simulation and finite-difference- time-domain （FDTD） method.展开更多
