UNIST ECE Nanostructured Photonic Devices Lab. (NPDL) researcher Daeik Kim, Hyeongju Chung, Jaeyeon Yu, Inyoung Hwang, Seongjin Park, and Prof. Jongwon Lee’s research paper entitled “Spin-controlled nonlinear harmonic generations from plasmonic metasurfaces coupled to intersubband transitions” has been published in Advanced Optical Materials. Advanced Optical Materials is one of the most prestigious journals in the field of Optics and Photonics.

In this paper, the authors experimentally demonstrated spin-controlled nonlinear harmonic generations from multiple-quantum-well layer loaded nonlinear metasurface. Based on combining giant second- and third-order nonlinearities of the multi-quantum-well structure with plasmonic nanoantennas with rotational symmetries, wavefront- and spin-controlled efficient second- and third-harmonic generations were achieved. Our metasurface may be applied to new light source generation, nonlinear holography, and nonlinear information processing, to name a few.
