TECHNIQUES AND APPARATUS FOR ALIGNING A LIGHT EMITTER WITHIN ITS PACKAGE Abstract A technique is disclosed for aligning a packaged optical emitter with its associated transmission fiber which provides peak power coupling between the emitter and the fiber. The technique uses a connectorized coherent fiber bundle which is inserted in the fiber connecting portion of the package such that it accepts the emitter output radiation at the same Z-axis position as the single fiber it simulates. The fiber bundle has a fiducial marking on one end which coincides with the core region of the single fiber. Both the emission pattern and the fiducial marking are displayed on a video monitor and the emitter subassembly is moved around inside the package until the emission pattern coincides with the fiducial, thus indicating alignment of the emitter with the associated transmission fiber.
