Second-Harmonic Generation in (111) Gallium Arsenide Nanoantennas

Not Accessible

Your library or personal account may give you access

Abstract

Dielectric nanoantennas have emerged in recent years as a promising platform for nanoscale second-harmonic generation (SHG) light sources and as building blocks for SHG metasurfaces. The group of III-V semiconductor materials with zincblende (ZB) crystal structure has played a key role in this development since it contains materials that feature high refractive indices and low losses in the near infrared (NIR), and strong second-order nonlinearities owing to the broken inversion symmetry in these crystals.
