	1	A novel model on dynamic resource allocation in optical networks显示文摘A novel model on dynamic resource allocation in the WDM optical networks is proposed, basing on the integrated considerations of the impacts of transmission impairments and service classification on dynamic resource allocation in the optical layer.In this model, the priorities of optical connection requests are mapped into different thresholds of transmission impairments, and a uniform method which is adopted to evaluate the virtual wavelength path (VWP) candidates is defined. The Advanced Preferred Wavelength Sets Algorithm (A-PWS) and the heuristic Dynamic Min-Cost & Optical Virtual Wavelength Path Algorithm (DMC-OVWP) are presented addressing the routing and wavelength assignment (RWA) problem based on dynamic traffic and multi priorities in wavelength-routed optical networks. For a received optical connection request,DMC-OVWP is employed to calculate a list of the VWP candidates, and an appropriate VWP which matches the request's priority is picked up to establish the lightpath by analyzing the transmission qualities of the VWP candidates.

	2	A modified split—step fourier method for optical pulse propagation with polarization mode dispersion显示文摘A modified split-step Fourier method (SSFM) is presented to solve the coupled nonlinear Schroedinger equation (CNLS) that can be used to model high-speed pulse propagation in optical fibres with polarization mode dispersion (PMD). We compare our approach with the SSFM and demonstrate that our approach is much faster with no loss of pre-chirped RZ(CRZ) formats in the presence of high PMD through this approach. The simulation results show that CRZ pulses are the most tolerant to high PMD values and the extinct ratio has a great impact on the transmission performance.

	3	The Signal Generator of Triphase Sine Wave显示文摘In the process of developing and adjusting the product in this project, we need some signal sources, which usually afford square or sine wave. Generally the square ware is used for digit logic, but for the analog signal wave is used to judge the linearity's qualities and other functions of the electric circuit. However the common ready-made signal sourceis all unidirectional sine wave, the signal sources whose phase shift can arbitrarily be regulatedand which have precise phase are still not available one the current market.
