Abstract
The spatial optical switch [or interconnection network (IN)] is one of the
more successful optical elements in optical communication networks. In fact, it is
one of the only commercially deployed all-optical elements and is probably the most
widespread after optical fibers themselves and optical amplifiers. Low port-count
switches are fairly easy to construct, but larger INs present interesting
realization challenges, especially when strictly nonblocking connectivity is
required. The Cantor network allows this high connectivity level, even for a large
network, but it has not received much attention in the literature. Here optical
implementation of the Cantor network is presented. The system is realized in a
recursive manner, thus eliminating the complex static interconnection patterns
usually required with this network.
