| 摘 要： | 提出一种基于长周期波导光栅的宽带集成Er-Yb掺杂磷酸盐玻璃集成波导放大器,其中增益平坦光栅滤波器直接刻蚀在有源波导上.放大器模型建立在考虑了上转换之后的传输与速率方程基础上,利用重叠积分与龙格-库塔相结合的方法进行求解.放大器的本征增益谱通过求解重叠积分龙格-库塔方程得到,放大器的有害增益峰由长周期波导光栅滤波器来消除.讨论了长周期波导光栅透射谱对放大器增益平坦的影响.数值计算结果表明,在1 532～1 565 nm范围内,放大器的平均增益约为20 dB,增益抖动小于3 dB.研究结果表明,该结构可有效地消除本征增益谱中的峰值增益,提高放大器的增益平坦带宽.

| Abstract: | A novel broadband integrated Er-Yb co-doped phosphate glass waveguide amplifier with a long-period waveguide grating(LPG) is proposed,for which the gain equalizer is directly fabricated in the active waveguide. The amplifier model is based on propagation-rate equations and includes both uniform and pair-induced up-conversion mechanisms. It is solved numerically by combining the overlapping integral and Runge-Kutta(RK) algorithms,and the intrinsical gain spectrum of the amplifier is obtained. The deleterious... |
