Self-alignment with optical microconnectors for free-space optical interconnections.
A self-alignment technique that uses optical microconnectors forthree-dimensional optics in optical computing systems and opticalinterconnections is proposed. The optical microconnector consistsof an optical plug and a socket. On the output plane of an opticalsystem, optical plugs are made of a photosensitive resin exposed tolight through the optical system. Because the correspondingpositions of the optical plugs are critical to the image formed by theoptical system, a detecting device can be aligned and mounted by theconnection of the optical plugs to sockets formed on the surface of thedevice. Optical microconnectors were experimentally fabricated in areflective block optical system. An alignment accuracy of ~20 mum was attained in the experiment.
