对用于光学向量矩阵乘法器的16路阵列光源和驱动电路进行了系统的研究。提出了采用商用分布式反馈激光器（DFB）和16路光纤阵列耦合的方式构造阵列光源模块，并且在驱动电路中设计了功率反馈自校正调节算法，解决了由于当前激光器制造工艺条件的限制而造成的各路激光器之间的阈值电流和P-I转换效率等参数差异问题。实现了光源系统各个通道间的输入向量数据和输出光强之间的一致性映射。实验结果证明，所研究开发的光源阵列不仅成本低，而且数据源信号的高频响应性能良好，保证了光学向量矩阵乘法器运算性能的稳定性和准确性。

Laser array with the scale of 1 ×16 for optical vector-matrix multiplier as long as its driven circuit was designed and implemented. A 1 ×16 laser array was constructed by coupling 16 commercial discrete distributed feedback (DFB) lasers with a 1×16 fiber array. Calibrating module adopting feedback algorithm was equipped with the laser array driven circuit, successfully solving problems encountered due to differences of threshold current and P-I conversion efficiency among lasers of the same type. And the same mapping relationship was acquired between the input vector and output intensity power among different channels of the source array. The proposed light source array system together with its driven circuit not only reduces cost, but also possesses excellent high-frequency response,ensuring the stability and accuracy of the optical vector matrix multiplier′s computing performance.
