"can be quickly toggled from light to dark and back, using low power to rapidly process/ store information using light particles... avalanching nanoparticles feature extreme non-linearity, emitting light whose intensity can increase massively with small increase in laser intensity... nanocrystals composed of neodymium doped: potassium, chlorine, lead... intrinsic optical bistability: can be either bright or dark under exactly same laser excitation wavelength/ power...  once emitting light, can cut back on power but retain same intensity"
