Of interest to anybody who has been following this discussion
should be this recent article:

%A Benjamin Arazi
%D January 1985
%T An Electrooptical Adder
%J Proceedings of the IEEE
%V 73
%N 1
%P 162-163
%X A prototype for a binary adder, in which the carry propagation is
handled by light signals is suggested, thus enabling a fast execution
of addition operation even for large operands.
