PDS: Also, some of my own random thoughts: Compare the idea of a laser (a resonating cavity, mirrors) at whatever scale -- with the idea of phase cancellation in sound... See, in the most generic description of a laser possible, there are two mirrors, one fully silvered, one half silvered, and as a result of continuing to add light energy into this cavity, by bouncing back and forth between both mirrors enough times, the light, which is "chaotically ordered" (for lack of a better term) on input, now becomes ordered (in a straight line) and coherent on output... Well, it might be that that could be done to any wavefront in classical physics -- but the thing is, for any type of wavefront in classical physics, you need a resonating cavity (the equivalent of the two mirrors), some way to pump energy into that cavity, and enough energy to get it past a certain threshold necessary to create coherency in the output... (Side thought: There may be some relationship wtih the discrete, non-contiguous energy levels of electrons in an atom's shells here, but that's a side discussion...) And then of course there are the thermal management issues that might arise when doing that... But that's not the point! Point is, in theory, it should be doable to any wave type in classical physics, be it sound, light, air, waves in the electromagnetic spectrum, etc., etc. And, it should also be doable at any level of the nano scale too, and that spacers/the use of surface plasmons exist and work -- could be thought of as a hint -- that this might be possible on all levels of matter someday (since matter/atoms/subparticles/substructures contain waves/energy at many levels...) What's one possible future application of all of this, if you can get all of that to work? Well, if you can A) Put a nano laser beam generator on a substrate; B) Create the substrate such that parts of it are made out of CD/DVD/Blu-Ray material; Then, in theory, the material can "write" to itself, that is, change its own state at the nanoscale. Now, if transistors could be made out of that CD/DVD/Blu-Ray material (or whatever other substrate future scientists would invent), then, if it could all be carefully orchestrated, what the end result would be is a "chip foundry" on a single chip... Basically, the chip (or crystal, or other substrate) basically "knows enough" about the relationships between matter, energy, space, chemistry and transistors -- to "write" a new transistorized (electrical or light) entity, to "create" a new microchip or "intelligent crystal", or what-have-you (describe it as you will...) But anyway, that would be one future application... We'll call it an "Atlantean Crystal" (for lack of a better term!) -- and leave it at that...
