Did you read in the technical description how they can not only generate light pulses but also light that has different spectrums (colors). With that in mind they now have the ability to build a transistor that can have numerous gate states. Base3, Base6 and Base9 are all possible with this.
Yes, I did read it carefully, several times. But I did not notice what you pointed out, and am glad you saw it. This really opens the sky even more than it first appeared, because now, electrical flow has multiple "flavors" as well as current, voltage, &tc. They really have discovered something larger than any single team of people can explore.
Note also that they described the invention as having "3 ports: Ground, amplifier, and light-emitting." You might think that _this_ number three has nothing to do with the ternary conversation we just finished, but in fact, the order of "ground, amplifier, and light-emitting" is a perfect way to express the three poles in their natural relationship to one another. Thus far we've been talking about 1, 0, and -1. But when you extend the structure into analog, you start talking about things like "ground, amplifier, and light-emitting."
For example, Hegelian dialectics is another way of looking at the relationship of these three positions. First there is the declaration and then there is an opposing response, and then arising from these two, there is a third "declaration" which is composed of insights derived from the spectrum revealed by the first two. Ground, amplifier, and light-emitting, if you're able to see the poetic insight weaving all of this together.
It's exciting to see that the very newest technology in transistor development is not only light-generating, but tripolar in structure.
