Abstract

Over the past decade, there has been extensive work in developing integrated silicon photonics (SiPh) gratings for the optical addressing of trapped ion qubits among the ion trap quantum computing community. However, when viewing beam profiles from gratings using infrared (IR) cameras, it is often difficult to determine the corresponding heights where the beam profiles are located. In this work, we developed transformer models to recognize the corresponding height categories of beam profiles in light from SiPh gratings. The models are trained using two techniques: (1) input patches and (2) input sequence. For the model trained with input patches, the model achieved a recognition accuracy of 0.924. Meanwhile, the model trained with input sequence shows a lower accuracy of 0.892. However, when repeating the model training for 150 cycles, a model trained with input patches shows inconsistent accuracy ranges between 0.289 to 0.959, while the model trained with input sequence shows accuracy values between 0.75 to 0.947. The obtained outcomes can be expanded to various applications, including auto-focusing of light beams and auto-adjustment of the z-axis stage to acquire desired beam profiles.

利用变压器模型识别硅光子光栅的光束轮廓。
在过去十年中,离子阱量子计算领域在开发集成硅光子(SiPh)光栅方面开展了大量工作,用于对被困离子量子比特进行光学寻址。然而,在使用红外摄像机观察光栅的光束剖面时,通常很难确定光束剖面所在的相应高度。在这项工作中,我们开发了变压器模型,用于识别来自 SiPh 光栅的光束剖面的相应高度类别。模型采用两种技术进行训练:(1) 输入补丁;(2) 输入序列。在使用输入斑块训练的模型中,识别准确率达到了 0.924。而使用输入序列训练的模型的识别准确率较低,仅为 0.892。然而,当重复模型训练 150 次时,使用输入片段训练的模型的准确率在 0.289 到 0.959 之间,而使用输入序列训练的模型的准确率在 0.75 到 0.947 之间。所获得的结果可扩展到各种应用中,包括光束的自动聚焦和 Z 轴平台的自动调整,以获得所需的光束轮廓。
