New Optical DSPs With Tera-ops Performance

GFD writes: "The EETimes has a story about a new class of hybrid digital/optical signal processors that are programmable and offer tera-ops performance potential for relatively low cost and power requirements. No fundamental breakthroughs but rather a very slick use of existing optical networking components to create a programmable optical processor that looks to the rest of the world like a single chip digital signal processor. Elegant and impressive if they can deliver."

Optical FFT==Digital FFT ??

I'm not sure that an optical transform is the same as a digital transform, or that they can be used to do the same thing. Can their optical FFT/digital encoding produce the same bits during JPEG encoding as a digital FFT/digital encoding JPEG encoder? This is crucial for image/video compression algorithms.
