No, I don't think so. I don't think that light can be used to replace all (metal) conductors on a silicon chip, at least in the near term. However, this technology has the potential of bringing performance gains to on-chip memories such as L1 and L2 caches as well as software configurable scratch pad memory. Other possibilities that spring to mind are faster core-to-core communications as well as bundling more cores on a same die as the faster communication makes physically larger dies possible. disclaimer: I work in the semiconductor industry but this is not my area of expertise, my speculation is as good as anyone else's.
