我们报告了全光时间积分器的第一个实验实现。该积分器使用基于叠加光纤布拉格光栅的全光纤有源（增益辅助）滤波器来实现，该光栅由铒镱共掺杂光纤制成，其行为类似于“光学电容器”。该器件的功能通过集成不同的光脉冲（持续时间低至 60 ps）以及集成具有不同相对相位（间隔最多 1 ns）的两个连续脉冲来测试。所开发的设备用于实现求解常微分方程的全光学计算系统的潜力也经过了实验测试。 (C) 2008 美国光学学会
We report the first experimental realization of an all-optical temporal integrator. The integrator is implemented using an all-fiber active (gain-assisted) filter based on superimposed fiber Bragg gratings made in an Er-Yb co-doped optical fiber that behaves like an 'optical capacitor'. Functionality of this device was tested by integrating different optical pulses, with time duration down to 60 ps, and by integration of two consecutive pulses that had different relative phases, separated by up to 1 ns. The potential of the developed device for implementing all-optical computing systems for solving ordinary differential equations was also experimentally tested. (C) 2008 Optical Society of America
