Facing the evolvement of the optical Grid technology, dynamic task scheduling can largely improve the efficiency of the Grid environment under the real circumstances. We propose a Serve On Time (SOT) algorithm - based on the idea of combining all the dynamic multi tasks so that all the tasks will obtain the rights to be served as soon as possible. We then introduce the basic First Come First Serve (FCFS) algorithm. A simulation will show the advantage of SOT.
By exploiting the symmetry of bidirectional wavelength-connections in WDM networks, we propose an NxN bidirectional OXC using one N/2xN/2 reversible optical switch to reduce the complexity of the OXCs. The feasibility...

In this article optical minimum-shift keying (MSK) modulation format in 9×40 Gbit/s wavelength-division multiplexing (WDM) spacing of 100 GHz transmission systems is investigated and compared with return-to-zero differential phase-shift keying (RZ-DPSK) and return-to-zero (RZ). The performance of optical MSK in presence of amplification noise, chromatic dispersion and nonlinear effects is analytically determined. Operations over a wide range of parameters, such as span input power, precompensation value, and chromatic dispersion parameter are performed;experimental results show that optical MSK demonstrates special performance in transmission distance, nonlinear effects, and dispersion tolerance.

This paper reports fiber Bragg gratings (FBGs) inscribed in a small-core Ge-doped photonic crystal fibers with a UV laser and a Talbot inter-ferometer. The responses of such FBGs to temper-ature, strain, bending, and transverse-loading were systematically investigated. The Bragg wavelength of the FBGs shifts toward longer wavelengths with increasing temperature, tensile strain, and trans-verse-loading. The bending and transverse- loading properties of the FBGs are sensitive to the fiber orientations.

We study the the storage capacity of slow-light tunable optical buffers based on fiber Brillouin amplifiers (FBA) through theoretical analysis. Gain saturation and pulse broadening are two key factors which limit the buffer capacity. It is shown that the maximum buffer capacity varies with data bit rate.
High energy Noise-like pulses has been generated from a passively mode locking fiber laser with large normal dispersion. Super-continuum more than 600nm can be generated directly by launching the pulses into high nonl...
