Abstract: Optical fiber array is a key component in the assembly of planar optical waveguide devices and enable greater channel counts than previously. However, assembling optical fiber array has been a challenge due to the stringent performance and reliability requirements posed by optical fiber communication applications. This paper investigates the causes of the failures involving the adhesive including: surface contamination, air entrapment, uneven curing, curing shrinkage; and thermal expansion coefficient mismatch.

Abstract: Aiming at problems of planar optical waveguide aligning and coupling multi-dimensional space sub-micron motion error, with using topology theory, estimating distribution of motion error paramount precisely, this paper establishes position model of precise motion platform, based on Monte Carlo method, obtains precise position distribution of fiber end point. The result indicated that this method can obtain accurate position in the adjust process of planar optical waveguide automatic aligning and coupling, and achieve effective control of aligning and coupling accuracy.
