2D atomically thin graphdiyne oxide (GDYO) nanosheets (NSs) are synthesized, and their nonlinear modulation is investigated. Generally, improving the modulation depth (MD) of all-optical modulation (AOM) requires a pump light with strong power, which limits the development of AOM technology in the design of low-power loss devices. In this study, an AOM system based on spatial self-phase modulation and spatial cross-phase modulation methods is proposed using 2D GDYO NSs. The results reveal that 2D GDYO exhibits tunable nonlinearity and high stab...
