摘要：
An on-chip dual-mode all-optical multifunctional logic operation unit including four AND and two OR logic gates is proposed and experimentally demonstrated. It is realized using multiple intra-mode four-wave mixing (FWM) processes in a multimode silicon waveguide for 2 x 10 Gbit/s non-return-to-zero on-off-keying (NRZ-OOK) mode-division multiplexing signals. The AND logic operation is realized via the non-degenerate FWM processes, and the OR logic operation is realized by overlapping the two degenerate FWM idlers in frequency domain via appropriately selecting the dual-mode pump wavelength. The two OR and four AND logic sequences are verified with NRZ-OOK sequences for both TE0 and TE1 modes.
