Physically, it seems to have been constructed with the third-gen Kindle as its dimensional blueprint, albeit with quite a different control scheme.

Dr Lin is already testing a waveguide designed to steer light with a wavelength of 1.5 microns, and he is also working on three-dimensional waveguides made of silicon, which will provide almost total control over the path the light takes, and make really complex optical circuits possible.
