摘　　要：通过理论计算和模拟对微纳光纤直径与入射波长变化对电场及能量分布的影响进行了研究,得到了在光纤直径以及入射波长与微纳光纤中电场和能量分布间的关系。结果表明,在光纤直径一定时,入射波长减小,微纳光纤中的电场模和能量密度时间均值增大,芯内约束的能量较多;而在入射波长一定时,光纤直径增加,光纤中的电场模和能量密度时间均值先增大后减小,而芯内约束的能量增大。Electric field and energy distributions depend on diameter and incident wavelength of micro/nano optical fibers are calculated and simulated theoretically, and the relationship between micro/nano optical fiber＇s diameter, incident wavelength, electric field and energy distribution are obtained. The results show that the smaller incident wavelength is, the larger electric field module and time average of energy density of micro/nano optical fiber are, and the more the energy restrains in the core when optical fiber＇ s diameter is constant. As the optical fiber＇ s diameter in- creasing, electric field module and time average of energy density of micro/nano optical fiber will increase at first and then decrease, but the energy restrained in the core will always increase when incident wavelength is constant.
