The relations between alignment deviation and coupling loss were analyzed based on beam propagation method. The optical tolerance of alignment deviation was studied based on the simulation results. It is found that the coupling loss is sensitive to the transverse dislocation, the second is the angle deviation, and the third is the axial gap. Moreover, when the coupling loss is 0.15 dB, the optical tolerance of the transverse dislocation is 1 μm, the optical tolerance of the angle deviation is 0.65°, and the optical tolerance of the axial gap is 16 μm. The simulation results are in good agreement with the theory results, the analysis for aligning and coupling of planar optical waveguide and array fibers is effective by beam propagation method..[著者文摘] Key words: planar optical lightwave; fiber array; coupling; beam propagation method 收稿日期: 2008-06-19 修订日期: 2008-09-18 基金资助: 基金项目：国家自然科学基金重点资助项目;国家“863”高技术研究发展计划项目（2007AA042344） 作者简介: 通信作者：段吉安（1969-），男，湖南冷水江人，教授，从事集成光子器件封装技术研究；电话：0731-8836858
