Year: 2026

Type: article

Abstract: esu, respectively. The formation mechanism of SSPM primarily arises from the interaction between coherent light and InP nanosheets. Leveraging the superior electronic coherence and photostability of InP nanosheets, four types of nonlinear photonic devices are designed and demonstrated, including all-optical switches, spatially asymmetric light transmitters, photonic diodes, and optical logic gates. This work not only bridges a critical gap in the third-order nonlinear optical research of III-V semiconductor nanomaterials but also opens new avenues for developing high-performance multifunctional nonlinear photonic devices.
