【摘要】 对一种高双折射光子晶体光纤的偏振模色散进行了测量.实验用26m长光子晶体光纤使皮秒光脉冲的两个正交偏振模产生了108ps时延.运用脉冲时延法和固定分析仪法对这种高双折射光子晶体光纤的偏振模色散进行了实验测量,测量得到其偏振模色散参量可达4154ps/km,对应的模式双折射度为1.25×10-3.这种新型的高双折射光纤可用于补偿光纤通信系统中的偏振模色散.更多还原

【Abstract】 The polarization mode dispersion in highly birefringent photonic crystal fiber is measured. In the experiment, the differential group delay of 108 ps was obtained by using a 26-meter-long PCF. Furthermore, PMD in this PCF has been measured by pulse delay method and fixed analyzer method. The result shows that the birefringence of the PCF is about 1.25×10 -3, and the high birefringent PCF can be used as dispersion compensation component in optical fiber communication system.更多还原
