Reconfigurable optical interconnection schemes are proposed and described which are based on optoelectronic holograms. Their interference patterns can be changed dynamically. To establish connections as free-space links, the light beams emitted from even hundreds of light sources are imaged onto an array of small dynamic holograms. Their interference patterns are optically and electronically controllable. These holograms diffract and focus each of the incident light beams individually onto the receiving photodiodes. By changing the hologram interference patterns dynamically, an optical switch is obtained. It renders the establishment of reconfigurable optical interconnections. Optoelectronic holograms as very-high-resolution spatial light modulators are proposed.
