基于介观尺度光纤的全光调控功能器件开发与应用研究

As an important photon manipulation method, light control is widely used in optoelectronic systems such as light sensing and optical communication etc. With the mesoscopic scale optical fiber as the research object, it is of great significance to develop new all-optical control function devices that meet the application requirements of information technology, laser and quantum communication. In this project, theoretical analysis and experimental research are carried on the optical absorption thermal properties, thermo-optic modulation efficiency, thermal stability and nonlinear modulation characteristics of mesoscopic scale waveguide including OM, OMC and GMF and their micro-nano optoelectronic devices. Furthermore, the project will focus on development of optical modulation modulator, tunable filter and other new functional devices. Relevant research results will provide a low noise phase carrier modulator for the fiber hydrophone system, provide a compact, simple, and easy-to-interconnect OMC tunable fiber filter for compact narrow linewidth ring Brillouin fiber laser, and develop an optical integrated high-speed modulator for optical fiber quantum communication system, which is expected to realize atomic thickness QKD photonic devices.
