Study of Signal Characteristics in WDM-PON using Injection Locked Fabry-Perot Laser Diode

주입광원에 따른 WDM-PON 에서의 통신 품질 특성 연구

We study signal characteristics of the injection-locked Fabry-Perot laser diodes(FP-LDs) for the development of a costeffective WDM-PON solution. The output power and system performance of WDM-PON using injection locked FP-LD are depend on optical characteristics of injection source. The effect of optical power and polarization state of the injection source experimentally investigated. We also measured BER characteristics of the directly modulated FPLD and its power penalty at the BER of $10^{-9}$.
