【摘要】 研究了各种啁啾和变迹的光纤光栅的制作技术 ,并分析了各种制作方法的优点和缺点 ,在此基础上提出用于高速光纤通信系统色散补偿的变迹啁啾光纤光栅的 3种制作方法。其中前两种方法灵活多变但精度稍差 ;后者精度较高但价格较贵。可根据实际情况选择合适的方法制作光纤。更多还原

【Abstract】 The fabrication techniques of chirped and apodised fiber gratings are introduced.The advantage and disadvantage of some kinds of fabrication techniques are also discussed.Three kinds of fabrication techniques of apodised chirped fiber gratings for high rate optical fiber communication system are proposed.The first two kinds of technique are flexible,but with low precision;the later in high precision but expensive.And the farametens of fiber gratings are fixed so the appropriate fabrication techniques should be selected according to actual situation.更多还原
