Frank, thanks greatly for that explanation. It switched the light in my head a bit brighter. I'm going to print this post and ponder the points made a bit and see how it applies to PHASIC. Thanks again.

Frank, Thanks again for eloquently explaining switching/routing of data. I guess you have to take into consideration the context the words are being used in since it can mean both. I got confused because my discussion with LUMM was specific to active devices which is the turning on and off or between the states of 0 and 1. The article refers to switching/routing but relates it to re-directing the pathway. This makes sense since the article talks about Nanovation which is promoting their optical resonator for optical switching. I now have to wonder, which market would be larger. DWDM chips which is what LUMM?s first product is or optical switches which Nanovation is pursuing.? The article states; "The photonics industry still has one major problem to overcome. Multiplexing is useful now for only extremely high-capacity lines traveling long distances because it has no effective system for switching or routing data and telephone calls" From what I have learned, the DWDM industry has been estimated to grow quite significantly in the next decade. This would mean both markets would appeal to any photonic company. I?m going to make an assumption that the advantages of PHASIC technology is not in the routing of the pathway but in other applications such as multiplexing/demultiplexing, on/off switching and other chip applications. Motorola who is a big chip maker must have interest in LUMM since they were reportedly at the grand opening of the plant. I would think that if LUMM had the ability to develop a competitive optical switch for routing, they would have pursued it. I hope the industry they have chosen is as big as anticipated. However, your following statement made me wonder if LUMM did have the capability of developing switches. "The switching entities that most often come to mind in telecoms are the electronic switching systems, or ESSs which are found in your local telco central office, generic cross-point switches, or matrix switches, like digital cross connect systems (DCSs), such as those made by Tellabs, Alcatel, LU, etc., T1 and SONET time division multiplexers, etc." The reason being Iraj went to France "on business" a while back and the only connection we posters could make was Alcatel. We have also made an assumption that Tellabs having connections with MOLEX could be a possible customer. At this point it?s all wishful thinking on our part. Hopefully the future brings it to reality. Some news articles stated some big customers but only time will tell. Anyway I wondered if LUMM actually does have the capability of developing routing switches from your above statement. Notice "generic cross-point switches, or matrix switches" and LUMM's web site included the product optical matrix switches which I mentioned in my previous post. Would an "optical matrix switch" be controlling the pathway and be the same matrix switch you mentioned? Your above statement was in the section explaining switching "A switch, in this sense, might connect one link, say, (a --> b) to another link, say, (c --> d) so that you end up with an end-to-end connection, or a resultant path, between a --> d. " This makes me wonder since "optical matrix switch" was included in LUMM's product line, is this the same as a routing switch which the article refers to? If so, why would Nanovations optical resonator be such a groundbreaking product? I now understand the different types of switching. Only confused what an optical matrix switch would do in comparison to routers/switches. Are they the same thing? Thanks again for any light you can shed on the matter. Tito
