光开关切换延时线芯片中各光开关的驱动电压标定和控制需使用多通道光功率计、可编程多通道电压源阵列等分立仪器，存在成本高、扩展困难的问题。设计并制作了一套低成本、易扩展的光开关切换延时线自动标定与控制系统，其中多通道光功率计模块可探测-53~-7.7 dBm内的光功率，误差小于0.5 dB；多通道电压输出模块可高精度稳定输出0~10 V的直流电压，输出电压波动小于±0.5 mV；使用单片机控制各模块协同工作并连接上位机实现人机交互。使用本系统对5-bit光开关切换延时线进行了自动标定和控制，结果显示，在32级延时状态下，延时线芯片输出端的透射光谱在1 560 nm波长附近的波动均小于1 dB，对应的延时步进为3.110 9 ps/state。该结果与商用仪器标定电压下测得的3.062 0 ps/state的延时步进高度吻合。本文设计制作的标定与控制系统精度高、成本低、扩展性强，具有很高的应用价值。

等离子体电极普克尔盒被广泛应用于大型激光驱动器中，用于抑制自激振荡、实现多程放大控制和反激光隔离，普克尔盒内的放电电极在长期使用过程中与腔内残余O₂发生反应出现退化现象，导致稳定性下降，寿命降低。为此，提出了封离型等离子体电极普克尔盒，其放电腔内的Ne气浓度可达99.9%，漏率小于1.0×10⁻¹⁰ Pa∙m³∙s⁻¹，理论使用年限大于40年。实验表明，封离型等离子体电极普克尔盒在工作20万发次后，其放电电极依然光亮如新，时间抖动仍稳定在6.4 ns附近，稳定性有了大幅提升。

本文设计了一种使用嵌入式Linux可编程控制的基于扫描反射镜的光开关，在触摸显示器的UI界面上进行光纤阵列通道间的具体切换操作。此外，还可以预先设定光开关的切换顺序、停留时间。光开关光路可自动对光校准来保证每个通道的输出功率最大。本文分析了此种光开关的设计原理，通过实验测试了光开关的性能。实验结果表明：当使用单模光纤阵列时，平均插入损耗小于17 dB，相邻通道间的平均串扰低于30 dB，相邻通道间切换时间小于1.3 ms；对于多模光纤阵列，平均插入损耗小于2.4 dB。本文所设计的光开关具有低损耗、低延时、高精度、高稳定性、高重复性、通道间串扰小、人机交互良好等优点，可用于波分复用器件、多路光波导传感器等光学器件的测试。

The basic indexes of all-optical integrated photonic circuits include high-density integration, ultrafast response and ultra-low energy consumption. Traditional methods mainly adopt conventional micro/nano-structures. The overall size of the circuit is large, usually reaches hundreds of microns. Besides, it is difficult to balance the ultrafast response and ultra-low energy consumption problem, and the crosstalk between two traditional devices is difficult to overcome. Here, we propose and experimentally demonstrate an approach based on inverse design method to realize a high-density, ultrafast and ultra-low energy consumption integrated photonic circuit with two all-optical switches controlling the input states of an all-optical XOR logic gate. The feature size of the whole circuit is only 2.5 μm × 7 μm, and that of a single device is 2 μm × 2 μm. The distance between two adjacent devices is as small as 1.5 μm, within wavelength magnitude scale. Theoretical response time of the circuit is 150 fs, and the threshold energy is within 10 fJ/bit. We have also considered the crosstalk problem. The circuit also realizes a function of identifying two-digit logic signal results. Our work provides a new idea for the design of ultrafast, ultra-low energy consumption all-optical devices and the implementation of high-density photonic integrated circuits.The basic indexes of all-optical integrated photonic circuits include high-density integration, ultrafast response and ultra-low energy consumption.
