Abstract:
1. A method of aligning an optical fiber array relative to an optical circuit device, the optical fiber array being coupled to the optical circuit device, the method comprising: coupling an optical signal source to one end of the optical fiber array, the other end of the optical fiber array being coupled to a side of the optical circuit device, the optical signal source adapted to transmit an optical signal to the optical fiber array; coupling an optical measuring device to the one end of the optical fiber array, the other end of the optical fiber array being coupled to the same side of the optical circuit device, the optical measuring device adapted to measure a characteristic of an optical signal received from the optical fiber array; establishing an initial optical path from the optical signal source to the optical fiber array to the optical circuit device to the optical fiber array and to the optical measuring device; measuring the characteristic of an optical signal received by the optical measuring device from the optical fiber array; and moving the relative position of the optical fiber array and the optical circuit device to change the optical path until the measured characteristic indicates that the alignment of the optical path is satisfactory.
