Reconfigurable interconnection using fixed regional angular volume holograms in photorefractive materials

摘要

We demonstrate a scheme of reconfigurable optical interconnections using angular multiple holograms in a photorefractive medium. The conjugation light paths of three regular interconnect configurations are stored and fixed. Real-time two-wave mixing with the forward read-out technique combined with a special optical imaging system is employed to achieve the incident angle of the input beam as changeable but the position has no shift. Issues about ability of reconfiguration, cross-over and energy efficiency are discussed theoretically. A proof-of-principle experiment is also presented. [References: 22]
