An optical pipeline architecture based on coherence modulation of ligh
t is advanced. The processing elements are formed by electro-optic mod
ulators set in series in which the data flow propagates from a low-coh
erence light beam. Initial experimental verifications are reported for
bulk devices and show that a potential computing speed of 10(11) addi
tions/multiplications per second can be expected. (C) 1995 Optical Soc
