SLD光源
SLD光源是一種像LED這樣光譜寬、像LD那樣亮度高的低相干光光源，從LD這樣的窄有源層發(fā)出的光與光纖有效耦合。SLD光源可用于光學測量和傳感器，包括光纖陀螺儀和光纖實驗室提供的光纖輸出SLD光源在不同的波長波段，從可見光到近紅外光。我們的產品線包括方便實驗的臺式類型和易于集成的模塊類型。

SLD與LD的區(qū)別
SLD與LD的區(qū)別在于端部表面是否存在反射。下圖中SLD和LD的結構幾乎是一樣的。在這兩個器件中,共同點在于活躍層(光發(fā)射層)夾在p-n型復合層(雙異質結構)上形成一個n型基質,通過p-n結上的的電極對活躍層施加電壓。不同之處在于光是否在活性層的端面反射。SLD在有源層的末端涂有AAR涂層以減少反射光，而LD的兩端表面被切割形成法布里-珀羅諧振器。
