摘要：
We have measured Brillouin frequency shift distribution in a planar lightwave circuit (PLC) by Brillouin optical correlation domain analysis (BOCDA). We have made an experimental system specialized for the measurement of PLC, realizing spatial resolution of 5.9mm with standard deviation of 0.34MHz in Brillouin frequency shift (BFS) measurement. From the data obtained in the experiments, we have found that the BFS distribution shape along the waveguide corresponds to its route pattern in the PLC.
