\begin{abstract}

This paper studies the problem of dedicating routes to connections in
optical networks. In optical networks, the vast bandwidth available in
an optical fiber is utilized by partitioning it into several channels,
each at a different optical wavelength. A connection between two nodes
is assigned a specific wavelength, with the constraint that no two
connections sharing a link in the network can be assigned the same
wavelength. This paper considers optical networks with and without
switches, and different types of routing in these networks. It
presents optimal or near-optimal constructions of optical networks in
these cases and algorithms for routing connections, specifically
permutation routing for the networks constructed here.
