摘要：
We report nondisruptive measurement of distributed mode coupling along a five-mode fiber (5MF) using a reconfigurable Brillouin optical time domain reflectometer (OTDR) based on programmable spatial light modulators (SLMs). Mode coupling between LP01 mode and higher order modes LP11a,b and LP21a,b is successfully characterized with a spatial resolution of 50 m. (C) 2014 Optical Society of America
