So if I make a 'photonic circuit'... doesn't some kind of electrical impulse have to modulate the light pathways, i.e. turning them on and off to allow light through, in order to create logic structure? i.e... doesn't this still require transistors? Or does this material actually *change* like a transistor gate when subjected to light, and change back when the light is taken away... Now that I could see making logic gates with.
