针对微波光子超宽带无线通信系统中对激光器阵列芯片的需求，开展了十通道大功率激光器阵列芯片设计，基于重构-等效啁啾光栅技术实现大功率激光器阵列波长精确调控，采用倒梯形脊波导结构提高载流子注入效率，稳定载流子分布；优化再生长工艺技术，提高出光功率并降低 RIN 值同时优化量子阱与波导，本数据集基于激光器阵列芯片、光电探测器、光谱分析仪、数字示波器等仪器产生，主要记录了激光器阵列芯片的波长、边模抑制比及RIN噪声。To address the demand for laser array chips in microwave photonic ultra-wideband (UWB) wireless communication systems, we designed a 10-channel high-power laser array chip. Precise wavelength regulation of the high-power laser array was achieved via the reconstructed-equivalent chirped grating technology. An inverted trapezoidal ridge waveguide structure was adopted to enhance carrier injection efficiency and stabilize carrier distribution. Additionally, the regrowth process was optimized to increase the output optical power and reduce the RIN value, while the quantum wells and waveguides were also optimized. This dataset was generated using instruments such as laser array chips, photodetectors, optical spectrum analyzers, and digital oscilloscopes, and mainly records the wavelength, side-mode suppression ratio (SMSR), and RIN noise of the laser array chips.
