All-optical binary counter

Poustie, Alistair J., Manning, R.J., Kelly, A.E. and Blow, K.J. (2000). All-optical binary counter. Optics Express, 6 (3), pp. 69-74.


We experimentally demonstrate an all-optical binary counter composed of four semiconductor optical amplifier based all-optical switching gates. The time-of-flight optical circuit operates with bit-differential delays between the exclusive-OR gate used for modulo-2 binary addition and the AND gate used for binary carry detection. A movie of the counter operating in real time is presented.
