The article is a bit confusing with its talk of "deflectors": the mechanism is actually diffraction, using the fact that longer wave lengths (red, or red+green=yellow) are affected more than shorter ones (green+blue=cyan or blue).
There was another thread about this, linking earlier news stories, but I cannot find it for now, and do not mind a new discussion of a promising idea. It seems limited to very small "camera-phone sized" pixels, small enough for diffraction to be a strong effect, but maybe larger sensors could use a great many of these tiny pixels and bin the data on-chip.
P. S. I found the eariler thread: http://www.luminous-landscape.com/forum/index.php?topic=74893.0
which links to the original Panasonic press release.
