Abstract

Author(s): Li-Hong Hong, Bao-Qin Chen, Chen-Yang Hu, and Zhi-Yuan Li We present a systematic theoretical investigation of second-harmonic generation (SHG) in a subwavelength lithium niobate (LN) single-crystal thin-film waveguide with birefringence in permittivity and refractive index and strong anisotropy in the nonlinear susceptibility ${χ}^{(2)}$. In a macroscopic... [Phys. Rev. A 98, 023820] Published Fri Aug 10, 2018
