| 摘要 |
The invention provides a method of manufacturing an optical printed circuit board and an optical printed circuit board. The method comprises providing a support layer; on the support layer, providing an optical core layer; forming optical channels from the optical core layer and surrounding the optical channels with cladding thereby forming optical waveguides; and during said step of forming the optical channels, forming one or more alignment features, e.g. projections, on the optical printed circuit board.
