　　報告摘要：
　　The demand for data has been increasing exponentially with very high growth rates from the access to data-centre interconnects and to long-haul transmissions. Further enhancement of the information capacity has been a perennial goal of scientists and engineering globally. A cost-effective solution for expanding the link capacity of optical interconnects is utilizing advanced multiplexing technologies. Currently, the most popular technologies include wavelength-division-multiplexing (WDM), polarization-division-multiplexing (PDM), mode-division-multiplexing (MDM), etc. As it is well known, silicon photonics is compatible with standard CMOS (complementary metal oxide semiconductor) processes and thus has attracted much attention as a very promising platform to build ultrasmall integrated photonic devices for large-scale photonic integrated circuits in the future. Silicon-based on-chip (de)multiplexers are really attractive and great progresses have been achieved in the past years, which will be reviewed in the talk. There are three parts. The first part is for high-performance wavelength-division-multiplexers, including arrayed-waveguide gratings (AWGs) and microring-resonators (MRRs) as the representatives. The second part is for high-performance PDM devices like polarizers, polarization-beam splitters (PBSs) and polarization rotators (PRs) as the representative on-chip polarization-handling devices. The third part for mode converters/ (de)multiplexers. Hybrid (de)multiplexers enabling more than one multiplexing technologies simultaneously will be discussed. As the link capacity increases dramatically, it is also becoming more and more important to develop smart photonic networks-on-chip so that the bandwidth/channels can be utilized optimally and flexible. One of the keys for realizing smart (reconfigurable) photonic networks is switchable / tunable photonic integrated devices. As silicon has a large thermo-optic (TO) coefficient as well as the large heat conductivity (~149W/m?K), it is promising to realize efficient thermally-switchable/tunable silicon-based photonic integrated devices with reduced power consumption. Our recent work on thermally-switchable / tunable silicon photonic devices with micro-/nano-heaters will be also reviewed.
