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(xué)測(cè)量和傳感器，包括光纖陀螺儀和光纖實(shí)驗(yàn)室提供的光纖輸出SLD光源在不同的波長(zhǎng)波段，從可見(jiàn)光到近紅外光。我們的產(chǎn)品線(xiàn)包括方便實(shí)驗(yàn)的臺(tái)式類(lèi)型和易于集成的模塊類(lèi)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(jié)構(gòu)幾乎是一樣的。在這兩個(gè)器件中,共同點(diǎn)在于活躍層(光發(fā)射層)夾在p-n型復(fù)合層(雙異質(zhì)結(jié)構(gòu))上形成一個(gè)n型基質(zhì),通過(guò)p-n結(jié)上的的電極對(duì)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。
