The attainment of high-quality wave concentration and manipulation has always been considered as state-of-the-art technology, especially for integrated photonics phononics. However, the prevention energy loss caused by backscattering or imperfections remains a grand challenge. With development topological phase matter, emergence insulators that support robust conductive edge states but insulating bulk waves provides possible solution. Nevertheless, existing can only achieve in...
We demonstrated an AlGaN-based multiple-quantum-well (MQW) deep ultraviolet (DUV) laser at 278 nm using a nanoporous (NP) n-AlGaN as the bottom cladding layer grown on sapphire substrate. The has very-low-threshold optically pumped power density of 79 kW/cm 2 room temperature and transverse electric (TE)-polarization-dominant emission. high optical confinement factor 9.12% benefiting from low refractive index is key to enable low-threshold lasing. I–V electrical measurement demonstrates that...
We investigate robust large-area elastic transverse wave propagation in an actively tunable membrane-type acoustic metamaterial. The waveguide with multiple degrees of freedom to control the width interface mode is realized by designing a heterostructure including three domains. One central domain constructed periodic unit cells ordinary state, where Dirac cone can be observed band structure. other two domains consist possessing opposite valley Chern numbers, respectively. By employing...
Abstract Rainbow trapping is of great significance for frequency-based wave splitting and broadband attenuation. By recognizing the deficiency prevailing gradient rainbow reflection devices in terms energy concentration vibration isolation, we design a new topological device by introducing protected interface mode (TPIM) into device. Therefore, beam composed homogenous rested on an alternate foundation constructed. Using theoretical numerical analysis, perform unit-cell band structure...
