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.
我们报道了全光时间积分器的首次实验实现。该积分器是通过基于在铒镱共掺杂光纤中制作的叠加光纤布拉格光栅构建的全光纤有源(增益辅助)滤波器实现的,其表现类似于一个“光学电容器”。通过对持续时间低至60皮秒的不同光脉冲进行积分,以及对相对相位不同、间隔达1纳秒的两个连续脉冲进行积分,测试了该器件的功能。还通过实验测试了所开发器件在实现用于求解常微分方程的全光计算系统方面的潜力。
