Hi Jim. You stated: "I should have been more specific. All-optical meant everything, including processors: computation." I don't know if I can go along with that. At least not where the foreseeable future is concerned. Here's why: Planar- or chip-based photonics are suitable for channeling, switching and perhaps even routing wavelengths, at some point. But all-optical components that would be needed for transistor-like switching, logic circuits and network mediation purposes still require a very large amount of real estate on substrates, which makes them less than ideal when it comes to meeting the needs of Moore's Law when densification comes into play. Also working against all-optical at the present time is the progress that's been made in the photonic (opto-electronic) realm in harnessing super-high frequencies and taming anomalies like dispersion into the hundred gigahertz and near-terahertz ranges. Such capabilities were thought to be the sole province of the all-optical domain only several years ago, but are now seen taking place in the electronic (and opto-electronic) space, instead, and achieving better economies, to boot.
