title: Corner-cube retroreflectors for optical chip-to-chip interconnections.
abstract: Corner-cube retroreflectors with the dihedral angles slightly different from a right angle are proposed for optical chip-to-chip interconnections. The spot pattern of the corner cube may follow the shift of the source and is approximately invariant to the incident angle. This retroreflective property substantially reduces the requirement for alignment accuracy. The design of a corner cube for given source and image positions using a ray-tracing algorithm and iteration procedure is presented.
