Abstract

We report an optical approach to addition/subtraction of quaternary numbers using nonlinearities and (D)QPSK signals. 50-Gbaud/s quaternary addition (A+B) and dual-directional subtraction (A-B/B-A) are demonstrated with 100-Gbit/s (D)QPSK. Power penalties <4 (addition) and 3dB (subtraction) are obtained.
