Even-order optical harmonics generated from centrosymmetric-material metasurfaces
Pavel Tonkaev, Fangxing Lai, Sergey Kruk +4
Generation of even-order optical harmonics requires noncentrosymmetric structures being conventionally observed in crystals lacking the center of inversion. In centrosymmetric syst…
Switchable optical trapping of Mie-resonant phase-change nanoparticles
Libang Mao, Ivan Toftul, Sivacarendran Balendhran +3
Optical tweezers revolutionized the manipulation of nanoscale objects. Typically, tunable manipulations of optical tweezers rely on adjusting either the trapping laser beams or the…
Wide-bandgap optical materials for high-harmonics generation at the nanoscale
Albert Mathew, Sergey Kruk, Shunsuke Yamada +2
High-order harmonics generation (HHG) is the only process that enables table-top-size sources of extreme-ultraviolet (XUV) light. The HHG process typically involves light interacti…
