Major Research Achievements

Ultra-long distributed optical fiber sensors (DOFS)

He is the first to demonstrate the implementation of the Brillouin amplification (BA) to phase-sensitive OTDR sensors (“Phase-sensitive optical time-domain reflectometry with Brillouin amplification”, Optics Letters, 39(15), pp. 4313-4316, 2014). Furthermore, with the combination of advanced fully-distributed amplification techniques based on RFL, Raman, and Brillouin effects, a phase-sensitive OTDR with the record distance of 175km is achieved very recently for distributed sensing (“175km Phase-sensitive OTDR with Hybrid Distributed Amplification”, PostDeadline Paper, OFS-23, Santander, Spain, June 2-6, 2014), resulting in the longest repeaterless DOFS in the world.

Random fiber laser

He is the first to demonstrate the application of the random fiber laser (RFL) to sensing (“Long-distance fiber-optic point-sensing systems based on random fiber lasers”, Optics Express, 20(16), 17695-17700, 2012). His work about high power RFL has been highlighted as one of the most exciting optics research in 2014 by Optical Society of America (“Random fiber laser: simpler and brighter,” Optics and Photonics News, 25 (December Issue), 30, 2014.).
Five papers related to RFL research as first/corresponding author have been cited by the prestigious review article “Random distributed feedback fiber lasers” in Physics Reports.
