Nikon patented a method a few years ago, where the sensor used a
dichroic mirror array over the sensor to separate colours. AFAIK they
didn't divulge a method to produce a dichroic mirror array at the small
pixel size expected for the idea to be useful.
For this Panasonic method, they state: "Micro color splitters are
fabricated using a conventional semiconductor manufacturing process"
There was some comment on DPReview from people who /seemed/ to know what
they were talking about, mentioning that pixel size to use the Panasonic
method needed to be < 1um.
