据日本《O Plus E》1992年第156期报道,日本东京工业大学研制量子线激光器,已成功地在室温下产生波长1.5μm的连续光振荡。用电子束(EB)把多重量子阱结构的发光层,制成宽30nm细线结构,量子线激光器可能用于通信。若量子线的宽度一定,密度增加,可得到的最高光电转换效率达90％以上。 According to Japan's “O Plus E” No. 156 in 1992 reported that Japan's Tokyo Institute of Technology to develop quantum wire lasers, has been successfully produced at room temperature wavelength 1.5μm continuous light oscillation. The multi-quantum well structure of the light-emitting layer is made of electron beam (EB) to a width of 30nm thin wire structure, quantum wire laser may be used for communication. If the quantum wire width is certain, the density increases, the highest photoelectric conversion efficiency available up to 90%.
