Speaking of optical computers,

	I heard of an effort underway at Caltech/Jpl to inter-connect an
array of computers use a hologram placed above an NxN array of CPUs.
Each CPU has a diode laser which is used to communicate with other CPUs.
This (allegedly) provides total inter-connect without wires.

	Does anyone have anymore information on this? One article I've seen
related to this is "... Fast Fourier Transform in a Light-connected 3-d VLSI"
by Hasegawa & Shigeo in 13th An. Symp. on Comp. Arch.
