Structural coloration generates colors by the interaction between incident light and micro- or nano-scale structures. It has received tremendous interest
Active metasurfaces have recently attracted more attention since they can make the light manipulation be versatile and real-time. Metasurfaces-based holog
We demonstrate the generation, spectral broadening and post-compression of second harmonic pulses using a thin beta barium borate (BBO) crystal on a fused
Valley topological photonic crystals (TPCs), which are robust against local disorders and structural defects, have attracted great research interest, from
Random fiber lasers have attracted extensive attention due to their rich physical properties and wide applications. Here, a novel random fiber laser (RFL)
High-order Laguerre-Gaussian (LG) petal-like beams have become a topic of significant interest due to their potential application in next generation optic
In the field of long-wave infrared (LWIR) thermal imaging, vital for applications such as military surveillance and medical diagnostics, metalenses show i
Lasers from ¹I₆ to ³F₄ transitions were first demonstrated in a Pr³⁺:YLF crystal by inserting a birefringent filter. Output powers up to 2.44 W, 2.10 W, 2
