Abstract
A method of aligning an optical fiber to an integrated optical circuit includes positioning the optical fiber at a first workstation such that a fast axis of the optical fiber is oriented at a first angular position, and securing the optical fiber to a glass block in that position. Then, positioning the integrated optical circuit at a second workstation such that a fast axis of the integrated optical circuit is oriented at the first angular position, and positioning the glass block and optical fiber at the second workstation with the optical fiber adjacent to the integrated optical circuit, so that the fast axis of the optical fiber is oriented at the first angular position. The free end of the optical fiber is illuminated, and the fiber is rotated until the integrated optical circuit detects a maximum throughput across the interface between the optical fiber and the integrated optical circuit.
