We present an improved design of a wavelength-tunable single-mode laser array based on a high order surface grating with non-uniformly spaced slots. The laser array consists of 12 slotted single-mode lasers. The fabricated device exhibits a quasi-continuous tuning range of more than 36 nm over the temperature range from 10°C - 45°C covering the full C-band. All lasers in the array have stable single-mode operation with side mode suppression ratio of 50 dB due to the modified slot design. A spectral linewidth of less than 500 kHz was obtained for all channels in the array.
我们展示了一种基于具有非均匀间隔狭缝的高阶表面光栅的波长可调谐单模激光阵列的改进设计。该激光阵列由12个带狭缝的单模激光器组成。所制造的器件在10°C至45°C的温度范围内表现出超过36 nm的准连续调谐范围，覆盖整个C波段。由于改进的狭缝设计，阵列中的所有激光器都具有稳定的单模运行，边模抑制比为50 dB。阵列中所有通道的谱线宽度均小于500 kHz。
