【摘要】 从纳米光纤倏逝波角度出发,采用时域有限差分法数值模拟了两根弯曲纳米光纤耦合区域附近的空间光强分布,给出耦合效率随两弯曲光纤间距、光纤半径、弯曲半径等参量变化的曲线.结果表明:两根纳米光纤之间可以有效传递光能,其耦合效率随两弯曲光纤间距、光纤半径、弯曲半径等参量均有关.更多还原

【Abstract】 Taking into account the evanescent wave of nanofiber,the distribution of light intensity near the two bending nanofiber was numerically calculated using the FDTD method.The coupling efficiency between the bending nanofiber versus diameter,bending radium and the distance between the two fiber was given.It is shown that there is evidence of coupling phenomenon between nanofiber.更多还原
