Abstract
The present disclosure generally relates to a method of optically coupling a photonic integrated circuit and an external optical component. In one aspect, a method comprises: providing a photonic integrated circuit comprising at least one integrated optical waveguide, the photonic integrated circuit having a cover layer; providing at least one optical component external to the photonic integrated circuit, the at least one optical component having an optical coupling facet and configured to be optically coupled to the at least one integrated optical waveguide, thereby forming an assembly; determining a position of the optical coupling facet of the at least one optical component in the assembly; determining a position of the at least one integrated optical waveguide; designing an optical interface pattern between the optical coupling facet of the at least one optical component in the assembly and the at least one integrated optical waveguide; and writing the interface pattern in the cover layer of the photonic integrated circuit by means of a femtosecond laser, thereby forming an optical interface for optically coupling the optical coupling facet and the at least one integrated optic…
