研究成果: Chapter同行評審


Passive optical network (PON) is considered as cost-effective optical access network architecture, and it has already been deployed all over the world. As the bandwidth demand continues to grow, optically amplified long-reach (LR) PON and wavelength division multiplexed (WDM) PON are currently under intensive studies for the next generation access networks providing higher capacity. Semiconductor optical amplifier (SOA) is a promising photonic device for these next generation access networks as a gain block to increase the power budget or as a colorless modulator in the WDM-PON. In this chapter, we will describe the basic principle and the characteristics of the SOA. After this, we will present some integrated devices using SOAs for the next generation access networks. Then we will demonstrate the applications of reflective SOA (RSOA) as the colorless optical networking unit (ONU) for the next generation signal remodulation WDM-PON and signal remodulation LR-PON.
