Abstract:
1. A method of fabricating an optical coupling module for optically coupling an optical fiber disposed on one side portion of a substrate with an optical waveguide mounted on the other side portion of the substrate in alignment with the optical fiber, comprising: a first step of forming a mask for anisotropic etching on the substrate; a second step of forming two mask patterns, which are self-aligned to a common axis and have different widths, on the mask through steps of: a third step of forming a first etched groove in which the optical fiber is disposed and a second etched groove in which the optical waveguide is mounted and which communicates with the first etched groove, simultaneously by anisotropic etching an exposed window of the two mask patterns; and a fourth step of mounting the optical waveguide in the second etched groove.
