日本某公司最近在光通信设备产品上使用了一种隐埋异质结构激光器,在工作波长为1.3微米时,其工作效率达43%.这种双通道平面型结构激光器在设计上做到了有效地阻止电流流入有效层任何一边区域内;而目前使用的各类激光器的效率则为20%或更低,这是因为有大量漏电流流入阻塞层而不经过激光 A company in Japan recently used a buried heterostructure laser on optical communications equipment products, achieving 43% efficiency at a working wavelength of 1.3 microns. The dual-channel planar structure laser was designed to be effective To prevent current from flowing into either side of the active layer, while the efficiency of the various lasers currently in use is 20% or less due to the large amount of leakage current flowing into the blocking layer without passing through the laser
