State Key Laboratory on Local Fiber-Optical Communication Networks and Advanced Optical Communication Systems

Introduction

The state key lab of advanced optical communication systems and networks was founded in 1989, and approved to open in 1995 by the government. The lab is ranked at the national level in optical communication research in China. The lab has two branches located at Shanghai Jiao Tong University and Beijing University, respectively. This brochure introduces the branch affiliated with Shanghai Jiao Tong University. The objective of the lab is to perform fundamental and applied research to push the forefront of the optical communications and networking technologies in China.

  • Currently the lab employs over 40 faculty and staff members consisting of 22 professors, 10 associate professors, and research staff, mainly in the electrical engineering and physics fields. Approximately 180 graduate students are working in the lab to carry out research to fulfill their degree requirements.


    Research Fields

    The lab performs inter-disciplinary research on communications, electronics, and optics. Some projects also require the interaction with researchers in computer engineering, math, and chemistry. The research areas are listed below:

  • Optical networks including automatically-switched optical networks (ASON) and optical transport network (OTN), next-generation packet networks, optical label and packet switching, multicasting and multi-granularity issues in optical networks.
  • Optical transmission including high-speed large-capacity systems, optical access systems, free-space optical communications, and optical wireless systems.
  • Opto-electronics covering passive and active components, integrated optical devices, modules and subsystems based on new materials and processes.
  • Information photonics including quantum communications and cryptography, signal processing, photonic crystal and fibers, nano-photonics, self-spinning opto-electronics, ultra-fast optics and optical sensing.
  • Software and hardware in optical networks, including design, implementation, and testing of communication protocols, network management, embedded systems, and programmable logic devices and circuits.

  • Research Achievements

  • All-optical Network: We have investigated all-optical communication network since 1996, and demonstrated several testbeds up to now. In 2003, we finished a heterogeneous automatic switched optical network (ASON) testbed, and then finished a multicast and burst-like ASON with GMPLS extension to support large scale TV delivery and e-Shanghai services in 2006. We have about 30 international conference invited presentations including those in OFC and ECOC, and three international standard documents, including RFC5814.

  • Wavelength-Selective Optical Switching: We started researching on WSS optical switching at the beginning of the century. We used electro-optical polymer and semiconductor optical amplifiers (SOA) to implement WSS, and built a test bet of optical burst switching (OBS). Fast data transportation including FTP and VoD was demonstrated. A US patent was granted and a European patent is in pending.
  • Novel Scheme of Phase-Correlated Signal-Generation: We propose and demonstrate a novel phase-correlated signal-generation scheme using all-optical Kerr shutter, which performs ultra-fast polarization to phase conversion. This scheme can break the speed limitation of conventional transmitters in generating phase-modulated formats. The experimental results at ultra-high rates (160G and above) have been reported in about 20 publications including IEEE/OSA Journal of Lightwave Technology invited paper, OFC/ECOC postdeadlines.
  • Novel Photonic Crystal Devices: We presented a novel three-port channel drop filter in two-dimensional photonic crystals, and derived the conditions for achieving 100% drop efficiency. In slow light waveguides, we found that zero-group-velocity modes could appear in index-uniform waveguide, which would make it possible to slow down and store photonic pulse in simple straight waveguides.
  • Quantum Optical Communication: We have investigated the quantum optical communication since 1996, including the quantum cryptography and quantum private communication, quantum network, and physical fundamental for quantum optical communication. We have published two books and more than 100 papers in the peer journals, and hold one US patent.
