Abstract

We propose and demonstrate all-optical simultaneous half-addition and half-subtraction of two return-to-zero on-off keying data streams using only two semiconductor optical amplifiers and without any assist light. In the experimental demonstration, we realize the arithmetic functions with an extinction ratio larger than 14 dB and achieve error-free signal processing at the repetition rate of 10 Gbit/s.
