Abstract
A free-space optical cross connect is proposed here that is highly compact
and uses digital microelectromechanical systems (MEMS) tip-style micromirror
arrays. Based on the Fourier cell, previously described for true time
delays, the cross-connect can be strictly non-blocking, or can be of
blocking or reconfigurably blocking designs to reduce the MEMS pixel count.
Because in the Fourier cell many systems can share a single spherical lens,
the hardware count is comparatively low and the system is highly
compact.
