Abstract

Nanowires with nonlinear optical properties such as second harmonic generation (SHG) are essential elements for an all-optical integrated photonic circuit. However, the existing materials face challenges for applications in a wide wavelength range. To cope with the challenges, ferroelectric nanowires are considered promising candidates, especially for SHG applications. In this Letter, we study SHG and waveguide properties in perovskite ${\mathrm{Na}}_{0.5}{\mathrm{Bi}}_{0.5}{\mathrm{TiO}}_3$ (NBT) nanowires. Strong SHG is observed in NBT nanowires illuminated by a 1064 nm laser radiation. For the waveguide studies, these NBT nanowires show a waveguide propagation loss as low as 0.01 dB/μm at 532 nm. This work suggests potential applications in future integrated optics with NBT nanowires.
