Abstract
Laser array with the scale of 116 for optical vector-matrix multiplier as long as its driven circuit was designed and implemented. A 116 laser array was constructed by coupling 16 commercial discrete distributed feedback (DFB) lasers with a 116 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.
