Academic Areas: Optical communications and Optical fiber sensing

Optical fiber as the ideal transmission medium of information, in terms of information access with the rise of internet things industry, attracts more and more attentions. Prof. Xia has carried out a series of research on the fiber technology, and has obtained the following achievements: (1) Through the introduction of multiple phase shifts in the fiber longitudinal period structure, a superbly narrow spacing multi-wavelength lasing fiber lasers has been achieved. It can be used in the beat frequency sensing; 2 The microstructure consisted of the fine-core and multimode fiber has been designed, and the measurements of the liquid level, the refractive index, the temperature and stress, etc, have been realized; 3 Aim to the chemical and biological sensing, the study of surface plasmon resonance (SPR) effect in the multi-core photonic crystal fiber reveals the coupling variation law from the partial coupled phenomenon to the fully coupled phenomenon; 4 In the breakpoint location technology of the optical fiber line, a new optical broadband chaos light source is adopted to fulfill simultaneously the multi-branch locations.
He has published 65 SCI papers with the total citations of 282. His H index of scholar has reached 10. He is currently the OSA member.
