摘要:

提出了一种修正的旋转单元电场矢量法(修正REV法),用于光学相控阵(OPA)天线阵初始条件的标定。该方法遵循类似的顺序单个天线相位校准过程,同时对算法进行了改进,避免了传统REV在初始相位分布较大和光功率测量精度有限的情况下可能出现的π相位误差。我们表明,该方法产生统计上更准确和可预测的校准结果,这是非常希望在实践中。

英文摘要:

This paper presents a modified rotating element electric field vector (modified REV) method to calibrate the antenna array initial condition of an optical phased array (OPA) device. The new method follows a similar sequential individual antenna phase calibration process while it modifies the algorithm to avoid possible π phase error in traditional REV when large initial phase distribution and finite optical power measurement accuracy present. We show that the method produces statistically more accurate and predictable calibration result which is highly desired in practice.
