A method of precision machining at least one cut into an article having a non-uniform surface, wherein the cut is of substantially constant depth relative to the non-uniform surface. One aspect of the invention is a machined optical wafer having two adjacent notches, to serve as a platform for a fiber optic pigtail, machined into the edge of the wafer. Another aspect of the invention is a method of automatically machining a plurality of notches into an optical wafer. For optical wafers having embedded light paths, light detected from these light paths may be used to compensate for the variation in embedded depth of the light paths.

Precision machined warped waveguide wafer

An optical waveguide component, with a pigtail attached thereto, is disclosed in which a portion of a surface of the component is bevelled and a portion of the endface of the pigtail is bevelled. The bevelled portion of the pigtail endface is oriented to be substantially parallel to the bevelled portion of the component surface or is oriented to be open with respect to the component surface. The pigtail endface can be continuously bevelled to form a substantially conical shape on the pigtail endface, wherein the substantially conical shape is offset from the optical axis of the pigtail.

Planar optical waveguides with low back reflection pigtailing

A method of manufacturing and testing integrated optical composites in which fiber pigtails are aligned with and attached to the optical output ports of a plurality of integrated optical components on a wafer, prior to separation into individual components. The multiple pigtails are arranged at the ends opposite the wafer, to facilitate optical connections during active alignment and measurement testing.
