Broadband second harmonic generation in GaAs nanowires by femtosecond laser sources

Hao He, Xiaoqing Zhang, and Xin Yan et al.

Nonlinear optical property of semiconductor nanowires plays a key role in nanoscale optoelectronics. In this paper, we demonstrate an excellent frequency converter based on GaAs nanowires (NWs), in which second harmonic generation (SHG) is excited by femtosecond lasers from 800 nm to 1800 nm. Simu ... [Appl. Phys. Lett. 103, 143110 (2013)] published Tue Oct 01, 2013.
