A 11D integrated optic wavcguide chip packaging system based on center-integration algorithm was designed and fabricated for adjusting the 11D positions of a waveguide in the space. The chip alignment can be realized quickly and precisely by the precision alignment and the improved center-integration algorithm. The packaging test among single-core fiber, channel waveguide and singlecore fiber shows that the average of end-coupling loss is 0. 113 6 dB, the maximum of single coupling loss is less than 0. 13 dB, the standard deviation less than 0. 02 dB, single coupling time less than 2 min and the whole packaging process time less than 5 min. The packaging produce among singlecore fiber array, 1 × 8 splitter coupler and 8-core fiber array shows that insert loss of every channel is less than 10.5 dB,the homogeneity index less than 0.4 dB, the single coupling time less than 5 min and the whole packaging process time less than 7 min. It is validated that the system can reach the commercial standard by the test data, which means that the system has good effect and practicability.
