We propose graphene-assisted multiple-input high-base optical computing. We
fabricate a nonlinear optical device based on a fiber pigtail cross-section
coated with a single-layer graphene grown by chemical vapor deposition (CVD)
method. An approach to implementing modulo 4 operations of three-input hybrid
addition and subtraction of quaternary base numbers in the optical domain using
multiple non-degenerate four-wave mixing (FWM) processes in graphene coated
optical fiber device and (differential) quadrature phase-shift keying ((D)QPSK)
signals is presented. We demonstrate 10-Gbaud modulo 4 operations of three-input
quaternary hybrid addition and subtraction (A?+?B?-?C, A?+?C?-?B, B?+?C?-?A) in
the experiment. The measured optical signal-to-noise ratio (OSNR) penalties for
modulo 4 operations of three-input quaternary hybrid addition and subtraction
(A?+?B?-?C, A?+?C?-?B, B?+?C?-?A) are measured to be less than 7 dB at a
bit-error rate (BER) of 2?×?10(-3). The BER performance as a function of the
relative time offset between three signals (signal offset) is also evaluated
showing favorable performance.
