光学空间模式控制器

观测芯片的输出波导数目，为通道数目；用任意波形产生器对芯片调制方波信号，通过示波器测得上升/下降沿10%-90%这一区间对应的时间，得到空间模式控制速度、相邻通道输出光谱的峰值的频率差为光谱分辨率。同时，文件中包含了芯片的仿真代码。The number of channels is determined by counting the output waveguides of the chip under test. Square-wave signals were modulated onto the chip using an arbitrary waveform generator, and the time corresponding to the 10%–90% interval of the rising/falling edge was measured with an oscilloscope to obtain the spatial mode control speed. The frequency difference between the peak frequencies of the output spectra of adjacent channels is defined as the spectral resolution. Additionally, the simulation code for the chip is included in the dataset files.
