Abstract
Techniques for dilating and reverse dilating optical channels in an optical system are disclosed. In one particular exemplary embodiment, a technique for dilating optical channels may be realized as a method for dilating optical channels in a system having W optical frequencies. The method comprises receiving a plurality of optical channels each operating at a respective one of the W optical frequencies. The method also comprises converting the optical frequency of each of the plurality of optical channels into a respective converted optical frequency defined by Δ+δ.f, wherein f represents the optical frequency of each of the plurality of optical channels, and wherein δ=±1 and Δ are constant for all of the plurality of optical channels. The method further comprises directing each of the plurality of optical channels based at least in part upon the respective converted optical frequency of each of the plurality of optical channels.
