结果表明，多电极泵浦可以显著提高量子阱半导体激光器在宽光谱范围内的输出功率。采用双电极泵浦的方法，在2~23 mW的输出功率范围内，获得了大于60 nm的光谱宽度。证明了通过多电极泵浦和中心波长切换控制40 nm以上20 nm半高宽(高斯分布)的单量子干涉仪SLD谱形状的可能性。用Mandel方法估算的SLD相干长度在2 mW输出时为7 mm，在23 mW时增加到11 mm。
It is shown that multielectrode pumping allows a significant increase in the output power of quantum well SLDs in the broad spectrum operating regime. More than 60nm spectral width at output power ranges from 2 to 23mW was obtained by two-electrode pumping of the active region of AlGaAs SQW SLD. The possibility of controlling the form of the SQW SLD spectrum by multielectrode pumping and central wavelength switching of a 20nm FWHM (Gaussian profile) over 40nm is shown. The coherence length of the SLDs estimated using the Mandel approach is 7mm at 2mW output, increasing to 11mm at 23mW.
