随着光纤通信系统的发展,长波(1.1—1.7μm)光源的研究巳广泛引起重视。因为在这一波长范围内,石英光纤具有低的传输损耗和材料色散。文献[1]指出,用InGaAsP/InP发光二极管(λ=1.3μm)作光源的系统的传输容量比目前常见的用GaAlAs/GaAs发光
With the development of optical fiber communication system, the research of long wave (1.1-1.7μm) light source has drawn great attention. Because of this wavelength range, quartz optical fiber has low transmission loss and material dispersion. The literature [1] points out that the transmission capacity of the system using InGaAsP / InP light-emitting diode (λ = 1.3μm) as the light source is higher than that of the common GaAsAs / GaAs
