Thorlabs 近红外超辐射发光二极管(SLD)
产品介绍
超辐射发光二极管(SLD)是 jue 佳 的高功率宽带光源,极其适用于诸如光学相干层析(OCT)成像系统和光纤陀螺仪(FOG)等应用。这里提供的蝶形封装SLD是一种磷化铟(InP)器件。此处提供的高达1100 nm的蝶形封装SLD是基于砷化镓(GaAs)基底,其余为磷化铟(InP)装置。

每个SLD都具有14引脚的蝶形封装,集成了半导体制冷片(TEC)和热敏电阻,以保证输出稳定性。它们的输出耦合到端接有2.0 mm窄键FC/APC接头的单模或保偏光纤中。请注意,光反馈会降低输出功率或损坏SLD。我们不建议将这些SLD与易于反射的组件一起使用,例如FC/PC接头。SLD1325 1325 nm超辐射发光二极管集成隔离器。如果您对具有集成隔离器的不同波长SLD感兴趣。
每个SLD发货时带有单独的产品数据表,包含仪器的光谱和工作参数信息。
此页面上的SLD具有近高斯或平顶光谱。中心波长的计算因这两种光谱形状而有所不同。
Thorlabs还提供定制波长或高功率二极管的低波动SLD。请注意,价格中包含了工程设计与晶片制造成本,因此购买数量不多时费用会很昂贵。

产品规格
由于生产具有超宽带宽的超辐射发光二极管的性质,下面出售的一些SLD具有近高斯光谱形状,而其他一些具有平顶形状。光谱形状的差异需要两种不同方法来定义中心波长,以便提供二极管的准确描述。
近高斯中心波长的定义
具有近高斯光谱形状装置的中心波长由相对幅度加权的平均值定义,并且由于光谱形状的可变性可能不对应峰值功率或FWHM中心波长。对于已知的光谱分析仪(OSA)轨迹:
其中
CW是 zhi 定 的中心波长
Xi为示踪数据点的波长
Yi为示踪数据点的振幅
平顶中心波长的定义
具有平顶光谱形状装置的中心波长由光谱上 zui 大 强度点以下位于3 dB的两个波长之间的中点定义。对于已知的OSA轨迹:
其中
CW是 zhi 定 的中心波长
XR_3dB是3 dB带宽的右波长边缘
XL_3dB是3 dB带宽的左波长边缘
