Abstract
We describe what we believe to be new designs for all-optical cross connects,
capable of wavelength conversion. They are based on two-dimensional,
space–wavelength, Benes or Cantor topologies, and they exploit cascaded wave-mixing
bulk frequency conversion. In these cross connects many channels at distinct
frequencies can be simultaneously frequency translated in a common wave-mixing
device, and a given lightpath may be converted many times between its input and
output. The new wavelength-interchanging cross connects are nonblocking and require
O{F log2W[log2(FW)]n} wave-mixing converters,
where n = 0, 1.
