    • The present invention discloses a low-cost light source for optical transmission systems and optical networks based on wavelength-division multiplexing (WDM) technology. A light source in accordance with the present invention is implemented by externally injecting a narrow-band incoherent light into a Fabry-Perot laser diode (F-P LD). After injection of narrow-band incoherent light, the output of F-P LD becomes wavelength-selective rather than multi-mode and the output wavelength of F-P LD coincide with the peak wavelength of the injected incoherent light. Multi-channel WDM light sources according to the present invention can be implemented using a single broadband incoherent light source and plurality of F-P LDs. An optical transmission system for upstream signal transmission in an passive optical network using the light source according the present invention is also disclosed.
    • 本发明公开了一种基于波分复用(WDM)技术的光传输系统和光网络的低成本光源。 根据本发明的光源通过将窄带非相干光外部注入到法布里 - 珀罗激光二极管(F-P LD)中来实现。 在注入窄带非相干光后,F-P LD的输出变为波长选择性而不是多模,F-P LD的输出波长与注入的非相干光的峰值波长一致。 根据本发明的多通道WDM光源可以使用单个宽带非相干光源和多个F-P LD来实现。 还公开了一种在根据本发明的使用光源的无源光网络中用于上行信号传输的光传输系统。
