1) Network architecture and switching mechanism: One major research topic in the field of optical network is to establish the architecture of optical network and develop the mechanism of all-optical switching. He proposed some new architectures for variable bandwidth elastic optical network with controllability and manageability. He also proposed some new structures for all-optical switching node based on this kind of network. The proposed architectures and structures can efficiently support the different applications for variable bandwidth elastic optical network.
2) Physical layer implementation: This is also one of major research topic in the field of variable bandwidth elastic optical network. He proposed some key technologies to implement the physical layer for this kind of network, such as more than 100G QPSK-PDM-SCFDM and 8QAM-PDM-SCFDM transmissions, all-optical multicasting based on co-polarized multi-pump four-wave mixing and based on polarization-interleaved multi-pump four-wave mixing, variable bandwidth coherent receiver, all-optical spectrum defragmentation, etc.
