This laser utilizes a Bragg grating fabricated in a high birefringence fiber as the wavelength-selective component, and then achieves the stable dual wavelength oscillation by introducing the polarization hole burning effect. Furthermore, by applying lateral strain upon the fiber Bragg grating (FBG), the space of the laser dual wavelengths can be tuned continuously.展开更多
文摘提出了一种新的波长选路算法-HCW算法,该算法综合考虑光路径跳数(H)、全网拥塞程度(C)以及链路最少剩余波长数(W)三个因素对路径选择的影响。对NSF网络的计算机仿真结果表明,该算法性能优于FAR(Fixed-Alternated Routing)、FPLC(Fixed Paths Least Congest)算法。
