active junction
解釋
有源結-
The high efficiency and high power semiconductor laser with multi - active regions, which are cascaded by reverse biased tunnel junction ( s ) can resolve the problems in theory and overcome these shortcomings
通過反向偏置隧道結將多個有源區再生耦合級聯起來的新型高效大功率半導體激光器從理論和實踐上解決了傳統激光器存在的上述問題。 -
In optical fiber aspect, the incident beam can be collimated, converted and focused by some kinds of lenses, making the mode of incident beam matched with or near the optical fiber ’ s modes. in this thesis, thorough theoretical analyses and experimental investigations were made for the external optical properties of a 980nm high - power tunnel junction regenerated multi - active - region quantum well stripe - geometry algaas / gaas / ingaas ld and three different stripe - width 980nm high - power
本論文圍繞本實驗室研發的新型隧道再生多有源區980nmalgaas / gaas / ingaas量子阱大功率半導體激光器和多種條寬的單有源區980nmalgaas / gaas / ingaas量子阱大功率半導體激光器的光場外特性、單模階躍折射率光纖和多模漸變折射率光纖的模場特性進行了深入的理論分析和實驗研究。 -
Graded doping is adopted in both sides of the junction ( double graded doping ). this results in a strong ( drift ) electric field throughout the whole active layer. this field will accumulate minority carriers effectively and the whole internal quantum efficiency is increased
漂移場的形成是通過mbe技術，在結的兩側都採用梯度摻雜（即雙梯度摻雜） ，從而在整個有源層都建立起一個強的（漂移）電場，有效地利用載流子在電場作用下的漂移作用收集少數載流子，使得總內量子效率得以提高。
