| Abstract(in English) | Passive optical networks (PONs) have been being installed to provide broadband services worldwide. In order to meet demands for higher transmission capacity beyond 10 Gb/s in access networks, the framework of next-generation passive optical networks has been discussed and proposed, such as time and wavelength division multiplexing (TWDM) PON systems. One of key building blocks for TWDM-PON systems is a low-cost colorless ONU transceiver module. For this purpose, a cost-effective tunable laser operating up to 10 Gb/s might be an enabling key component in next generation access networks. Tunable lasers have been developed and widely used for dense WDM systems in core/metro networks, however we need some different aspects for access networks, such as low-cost, uncooled operations, energy efficiency and so on. In this paper, tunable lasers are reviewed for colorless ONUs in next-generation access networks. In particular, advanced VCSEL technologies toward athermal and widely tunable operations, ultra-high-speed & low-chirp direct modulation, and ultra-compact modulator integration are presented. Also, compact, athermal and tunable filters will be discussed. |
