展望

雖然我們成功地以修正過後的分段式接點法量出量子點元件精確的增 益及吸收頻譜，然而若將改良型分段式接點法應用在量子井元件上，仍有 些問題尚待克服，比如說，量得的增益不夠大，或是雜亂的增益頻譜，其 或許肇因於蒸鍍於輸出鏡面的抗反射層。因為我們的量子井元件用的抗反 射層和本論文中量子點元件所使用是一樣的，如圖 3.7 所示，反射率最低 點在靠近 1400nm 左右，然而，我們的量子井元件輸出波長不屬於這個波段 (在小於 1000nm)，因此造成不合理的輸出光。

在本論文中我們討論了以多段式元件為基礎所量測的增益及吸收頻 譜，然而多段式元件的應用絕非僅止於此，在製程技術與量測系統皆已具 備下，可以開始極具潛力的多段式接點量子點超冷光二極體元件的研究，

藉著調變每一段的長度和注入電流，甚至是將吸收區施加不同程度的負偏 壓去努力，得到各種元件結構之頻寬與輸出功率的最佳化。
