No, sure, it's not for tomorrow. And it will never be as powerful as current high-end processors due to some diffraction issues, except if some current research on sub-wavelength light confinement prove to be successful.
But there are many areas where we don't need the power of current cpus. Most offices, as an example, would be just fine with PIII-equivalents for everyday work. And using light, there are things like Fourier transform which can be done much, much faster than with current electronic components...
I think that all-optical computing has its place in a long-term future. But only time will tell.
