A 9-channel wavelength tunable single-mode laser array based on slots is presented. The fabricated laser array demonstrated a threshold current in a range of 19~21 mA with the SOA unbiased at 20°C under continuous wave condition. Stable single mode performances have been observed with side-mode suppression-ratio (SMSR) > 50 dB. The output power higher than 37 mW was obtained at the SOA injected current of 70 mA for all the 9 channels within the laser array. A wavelength quasi-continuous tuning range of about 27 nm has been achieved for the laser array with the temperature variations from 10°C to 45°C. This array platform is of a single growth and monolithically integrable. It can be easily fabricated by standard photolithography. In addition, it potentially removes the yield problem due to the uncertainty of the facet cleaving.
本文介绍了一种基于狭缝的9通道波长可调谐单模激光阵列。所制备的激光阵列在连续波条件下，当半导体光放大器（SOA）在20°C无偏置时，阈值电流在19~21 mA范围内。观察到稳定的单模性能，边模抑制比（SMSR）> 50 dB。对于激光阵列中的所有9个通道，在SOA注入电流为70 mA时，输出功率高于37 mW。随着温度从10°C变化到45°C，该激光阵列实现了约27 nm的波长准连续调谐范围。该阵列平台采用单次生长且可单片集成。它可以通过标准光刻轻松制备。此外，它可能消除由于刻面切割不确定性导致的成品率问题。
