Broadband Second-Harmonic Generation From Electrically Tunable Nonlinear Polaritonic Metasurfaces
2020 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO)(2020)
摘要
We report broadband second-harmonic generation based on Stark-tunable intersubband nonlinearities in multiple-quantum-well structures combined with plasmonic nanoresonators. Experimentally, 0.75 mu m of the second-harmonic generation spectral peak tuning around pump wavelength of 9.8 mu m was achieved. (C) 2020 The Author(s)
