Research and development of optical components for optical networks in Tsinghua Univ.

Abstract

The Information Optoelectronic Technology Research Institute (IOTRI) in Tsinghua University brings together research activities and research projects in various optoelectronic devices, integrated photonic devices, optical fiber telecommunication and networks, optical display, optical storage and optical fiber sensing systems. The researches on the optical components for the all optical networks are executed in the area of Fiber Bragg Grating, Wavelength Converters, Tunable filters, Fiber Amplifiers, DFB+EA integrated light source chips and modules, optical nonlinear macromolecule material and its application, Fiber Amplifiers, etc. and the forecast researches on photonic crystal and nanophotonics are also started. Up to now, about 10 research projects on optical component for all optical networks are kept on going in IOTRI with the projects supports by the government through the National High-tech R&D Program ("863" program), the National Fundamental Research and Development Program (“973” Program), the National Natural Science Foundation (NSFC), Tsinghua 985 Project, Foundation project of Tsinghua University, and some cooperated projects. All these projects cover the following research areas: Fiber Bragg Grating and its application in DWDM systems such as broadband dispersion and dispersion slope compensation, polymer optical waveguide and its applications, photonic crystal's theoretical analysis and design, wide-band dynamic gain equalized FRA+EDFA hybrid module and related components, wavelength converters and its application in optical networks, tunable PMD compensators, Fiber optical parametric amplification, Gain Coupling in high-speed integrated light sources, etc. Some projects are just carried on, and some of them achieved a lot. About 30 papers in the above areas are posted in the last 3 years.
