First off, the reason you want light for transmission on chips isn't because it is "faster", it is because it is less susceptible to electromagnetic interference. The speed of light in a medium is the speed electronic signals travel, and the speed light waves travel. However, electronic signals bleed interference, and light waves don't. You also can switch light waves on and off at theoretically higher rates, with less power, so optical signals can break the 4 GhZ barrier we are currently stuck at. Secondly, they can't bend light without loss. Just with less loss. But the interesting part of the paper is the fact that the turning is selective depending on polarization (one polarization turns, and one doesn't). They are also able to turn light very quickly, compared to the wavelength of the light. So the radius of curvature divided by the wavelength of the light is around 6.4 for this paper.
