Multi-wavelength laser arrays (MLAs) with a high wavelength-spacing precision are designed and fabricated. The MLAs are realized by the reconstruction-equivalent chirp (REC) technique, and anti-reflection structures are used to decrease the wavelength deviation. Six multi-wavelength laser arrays are fabricated and tested. Statistical results show that 81.1% of all 95 lasers have wavelength deviations within ±0.1 nm, and all of them are within ±0.2 nm. The mean wavelength spacing is 1.605 nm, and the standard deviation is 0.132 nm.
设计并制造了具有高波长间隔精度的多波长激光阵列（MLA）。这些MLA通过重构等效啁啾（REC）技术实现，并采用抗反射结构来减小波长偏差。制造并测试了六个多波长激光阵列。统计结果表明，在所有95个激光器中，81.1%的激光器波长偏差在±0.1 nm以内，且所有激光器的波长偏差均在±0.2 nm以内。平均波长间隔为1.605 nm，标准偏差为0.132 nm。
