Abstract
A technique for selectively frequency translating optical channels in an optical network is disclosed. In one exemplary embodiment, the technique is realized as a method for selectively frequency translating optical channels in a system having W optical frequencies. The method comprises selectively directing an optical channel operating at a respective one of the W optical frequencies based at least in part upon the respective optical frequency of the optical channel. The method also comprises shifting the respective optical frequency of the selectively directed optical channel by an amount defined by ±2i&Dgr;f, wherein &Dgr;f is an optical frequency spacing between adjacent optical channels, and i=0, 1, . . . log2W−1.
