英文摘要： To develop new optical passive device and meet the requirement of rapid development of broadband optical fiber communication network, optical fiber sensing network and the Internet of things, this project investigates the mode coupling, formation mechanism and transmission characteristics of superimposed fiber gratings (SIG) writing in the Refractive Index Guiding Photonic crystal fiber (RIG-PCF). It focuses on some scientific issues such as mode coupling model of SIG, the changing mechanism of the refractive index during the multiple-exposure process of superimposed fiber gratings fabrication, the transmission spectra of SIG effect infectors (overlap length, position, refractive index variation value), and the effect of fiber deformation on the SIG's properties etc. Moreover, the exposure control technique, overlap length and position control technique, fiber deformation control technique in the production process and optical properties of RIG-PCF SIG will be studied, after that the SIG's application will be explored. The final research objectives is to establish the mathematical model of the RIG-PCF SIG, reveal the optical properties, temperature characteristics and mechanical characteristics law of change to structure parameters, form the fabrication technology of RIG-PCF SIG, fabricate the RIG-PCF SIG with high quality, and provide new passive optical device for the all optical networks and the photoelectric industry ultimately.
