Abstract: Optical apparatus comprises: a wafer having an optical sub-assembly, and at least one groove, the groove being empty of any optical fiber and being for subsequent placement of a single mode optical fiber; at least one optical component fixed on the optical sub-assembly in a direction being optically aligned with the empty groove; such that as said subsequent placement is carried out, said single mode optical fiber is aligned with said optical component to the extent needed for single mode operation.
Abstract: A method of aligning an optical fiber with an optical component in a micro-optical sub-assembly, comprises: providing a groove in the micro-sub-assembly in alignment with the optical component; and placing the optical fiber in the groove, thereby aligning the optical fiber with the optical component. In this way a placement tool with an accuracy of 50 microns can be used to place an optical fiber with an alignment accuracy of one micron.
