Abstract
An alignment apparatus and an alignment method that enables to align an optical device with a receptacle, where the optical device and the receptacle have respective axes tilted to each other. The method includes steps of: (1) obtaining a minimum pressure caused to the optical device from the receptacle as varying a rolling angle around the X-axis of the optical device but fixing the pitching angle around the Y-axis at a rotating angle around the Z-axis; (2) determining a rotating angle where thus obtained minimum pressure becomes the minimum; and (3) iterating those procedures until the rotating angle obtained as varying the rolling angle and another rotating angle obtained as varying the pitching angle substantially coincides to each other.
