Multistate Tuning of Third Harmonic Generation in Fano-Resonant Hybrid Dielectric Metasurfaces
Omar A. M. Abdelraouf, Aravind P. Anthur, Zhaogang Dong +6
Hybrid dielectric metasurfaces have emerged as a promising approach to enhancing near field confinement and thus achieving high optical nonlinearity using low loss dielectrics. Add…
Continuous wave second harmonic generation enabled by quasi-bound-states in the continuum on gallium phosphide metasurfaces
Aravind P. Anthur, Haizhong Zhang, Ramon Paniagua-Dominguez +5
Resonant metasurfaces are an attractive platform for enhancing the non-linear optical processes, such as second harmonic generation (SHG), since they can generate very large local…
Demonstration of second harmonic generationin gallium phosphide nano-waveguides
Aravind P. Anthur, Haizhong Zhang, Yuriy Akimov +4
We designed, fabricated and tested gallium phosphide (GaP) nano-waveguides for second harmonic generation (SHG). We demonstrate SHG in the visible range around 655 nm using low pow…
