一、前言光纤通信是英国伦敦大学毕业的华人——高锟于1966年提出的。1970年美国康宁公司制出0.8～0.9μ波段传输损耗为20dB/Km的光纤,标志着光纤通信研制工作的开始。1974年贝尔实验室制出了1.06μ损耗1dB/Km的光纤。1976年日本制出了波长1.3μ损耗0.5dB/Km的光纤。1978年制出了波长1.55μ损耗低到0.2dB/Km的光纤。1980年制出了0.9～1.8μ整个波段损耗均在1.5dB/Km以下的光纤。光纤通信的最佳光源——半导体激光器的研究也步步紧跟,有所突破。1970年,在短波长0.8～0.9μ波段上使用的GaAs/GaAlAs双异质结激光器实现
I. Introduction Optical fiber communication is a Chinese who graduated from the University of London in the United Kingdom - Charles Kao was put forward in 1966. In 1970, Corning made a fiber with transmission loss of 20dB / Km in 0.8 ~ 0.9μ band, marking the beginning of the development of optical fiber communication. In 1974, Bell Labs made 1.06μ loss of 1dB / Km optical fiber. In 1976, Japan made a fiber with a wavelength of 1.3μ loss 0.5dB / Km. In 1978 made a wavelength of 1.55μ loss as low as 0.2dB / Km optical fiber. 1980 produced 0.9 ~ 1.8μ the entire band loss are below 1.5dB / Km optical fiber. The best source of optical fiber communication - semiconductor laser research is also followed by step by step, a breakthrough. 1970 GaAs / GaAlAs Double Heterojunction Lasers Used at Short Wavelengths of 0.8 to 0.9μ
