In this paper, the optical transmission equation of fiber considering fourth-order dispersion and quintic nonlinearity is proposed. Simulation software of ultra-long haul transmission is developed by discretizing the equation with symmetric spilt-step Fourier method. Unrepeatered optical transmission system of 40Gb/s signal centred at 1550nm is designed. The results of numerical analysis show that...
We present a reconfigurable neural processor for real-time simulation and prediction of opto-neural behaviour. We combined a detailed Hodgkin–Huxley CA3 neuron integrated with a four-state Channelrhodopsin-2 (ChR2) model into reconfigurable silicon hardware. Our architecture consists of a Field Programmable Gated Array (FPGA) with a custom-built computing data-path, a separate data management system...
We propose an improved ant colony algorithm for dynamic traffic grooming (IACA-DTG) in asynchronous optical packets switching networks, by using of the ratio of available wavelengths and path chosen length each iteration and the dynamic information updated on the available instant wavelengths in full network, which can implement traffic grooming under shorter path and less iterations. The algorithm...
