Spatial self-phase modulation (SSPM) is widely used to characterize the nonlinear refractive index of two-dimensional layered materials and design passive nonlinear photonic devices. In this work, we investigate the SSPM phenomena of black phosphorus

Circular dichroism (CD) spectroscopy is a typical technique to detect the chirality of an object. Due to the mismatch between light wavelength and the size of molecules, CD signal generally tends to be very weak in natural materials. In this work, we

Compared with the on-axis vortex beam and the off-axis single vortex beam, the off-axis double vortex beam has more control degrees of freedom and brings rich physical properties. In this work, we investigate theoretically and experimentally the gene

In this work, SSPM effects of VP Ns and their reaction dynamics were studied for the first time (left). Using the superior coherence electronic nonlinearity of VP Ns, all-optical switches based on the SSPM effect (right) were prepared.

Second-harmonic generation and third-harmonic generation have been widely investigated in nonlinear topological photonics. However, due to the weak nonlinear effect and the strict phase matching condition, it is a challenge to observe the high-order
