| 摘要 |
The present invention discloses a reconfigurable optical interconnect apparatus that redirects an optical beam through embedded holographic elements of a substrate-mode hologram to connecting information processors or to photonic switching devices. The apparatus includes a substrate-mode hologram, including a polarization insensitive input hologram member, one or more embedded polarization sensitive hologram members that couple transmitted diffracted or non-diffracted light to respective optical receivers. The optical receivers further couple the light out of the substrate-mode hologram or to cascaded similar apparatus. The method includes processing an incident beam of polarized light through a controlled polarization modulator, through an optical information encoder, such as a spatial light modulator, then further processing the polarized light through the substrate-mode hologram. The apparatus has advantages of being compact and expandable into larger systems.
