Abstract
A method of attaching an optical fiber to an IOC includes the step of forming an alignment groove in the waveguide surface of the IOC by utilizing a laser ablation system to remove a predetermined portion of the IOC material. Next, a dicing saw or other cutting means is used to cut into the IOC at a depth less than the thickness of the IOC, the cut forming a cut surface which is normal or at an angle with respect to both an optical axis of the waveguide and to an axis of the alignment groove, such step of cutting performing the additional function of optically polishing the cut surface. Next, an optical fiber is disposed within the alignment groove, and the fiber core is optically aligned with the optical axis of the waveguide by translational and rotational positioning of the fiber end face adjacent to the cut surface. The fiber end face is then secured to the cut surface with adhesive or other suitable means, and the fiber is attached to the IOC within the alignment groove with adhesive or other suitable means.
