Abstract
Abstract A method for making a cover for an integrated optical circuit, a cover for an integrated optical circuit, and an integrated optical circuit made with this cover are proposed. The method serves to minimize the effort and expense in integrating optical components in fiberoptical systems. An optical element 29 is placed in a molding die (10) with adjusting elements (13) that adjust the optical component (29) in its position, and a curable liquid is cast all around the optical component (29), and after it solidifies, this liquid forms the cover (25).
