Optical Component Alignment Using Marking Sets for Waveguide Coupling

The patent uses optical copies (images) of the physical optical components and their marking sets to perform alignment. Instead of directly manipulating the physical components during alignment, the system creates optical copies through cameras and processes these copies to determine relative positions and orientations, thereby achieving precise alignment without complex active adjustment mechanisms.

The patent replaces active mechanical alignment methods with an optical measurement and computational approach. Instead of using mechanical feedback systems to actively adjust component positions, the system uses optical cameras to capture marking sets, processes these images computationally, and derives alignment information, substituting mechanical complexity with optical and computational simplicity.

The patent applies preliminary action by incorporating marking sets into the optical components during the manufacturing process. These marking sets are pre-positioned with known geometric relationships to the optical elements, allowing for precise alignment to be achieved passively during assembly without requiring stringent manufacturing tolerances on the optical components themselves, as the markings provide the reference framework.

The marking sets serve as intermediary elements between the optical components and the alignment process. Rather than requiring direct precise manufacturing of the optical components themselves, the markings act as mediators that encode positional and orientational information, allowing the actual alignment to be performed with relaxed tolerances by reading these intermediary markers during assembly.
