     Another nice thing about optical computing is the ability to represent
     and compute in multiple levels of logic.  Imagine ternary or other
     higher radices used for computation.  Now, whether this is possible
     or not, depends a lot on the scalabilty of detector technology.

     Frequency separation and Intensity level separation provides two
     dimensional representation.  Fourier transforms will be simple
     mixing of two light signals (That was a guess, based on my rusty
     knowledge of signal processing. So be nice if you think it warrants
     flaming).   It might ressurect analog computation. 

     If optical computing becomes commonplace, what would be the equivalent of
     MIPS and FLOPS? MQPS (Million Quanta per second :-))

P.S.1:  The most corrupted version and abuse of MIPS is B(illion)IPS.
