Lithium niobate is a material that exhibits outstanding electro-optic, nonlinear optical, acousto-optic, piezoelectric, photorefractive, and pyroelectric properties. A thin-film lithium niobate photonic crystal can confine light in the sub-wavelength scale, which is beneficial to the integration of the lithium niobate on-chip device. The commercialization of the lithium niobate on insulator gives birth to the emergence of high-quality lithium niobate photonic crystals. In order to provide guidance to the research of lithium niobate photonic crystal devices, recent progress about fabrication, characterization, and applications of the thin-film lithium niobate photonic crystal is reviewed. The performance parameters of the different devices are compared.

利用自由空间耦合技术,用超短脉冲激发亚毫米尺度对称金属包覆波导中的超高阶导模,提出一种脉冲展宽的新方法。由于超高阶导模的强色散性质,经过短距离的传输,即可使脉冲宽度迅速展宽。理论分析表明,1 ps的光脉冲在光波导中传输毫米量级距离后,脉冲展宽因子可达到1000倍。
