Spectrum broadening of high-efficiency second harmonic generation in cascaded photonic crystal microcavities

Ren, Fang-Fang; Ye, Jiandong; Lu, Hai; Zhang, Rong; Zheng, Youdou

Description

An effective approach is proposed to broaden the spectrum of high-efficiency second harmonic generation in a one-dimensional photonic crystal based on the cascaded structure. By controlling the thickness of the joint layer, it is possible to realize a flat-top or quasiflat-top impurity band centered at the fundamental wavelength due to mode splitting effect in coupled cavities. Simulation results reveal that the spectrum of generated second harmonic exhibits a hump-like or multi-peak profile...[Show more]
