研究了中心对称光折变晶体中Kagome光子晶格内带隙孤子的存在及其稳定性。结果表明:带隙孤子只存在于半无限带隙内,中功率的带隙孤子是稳定的,高功率和低功率的带隙孤子是不稳定的。在高功率和中功率区域内,带隙孤子的功率随传播常数的增加而减小。在低功率区域内,带隙孤子的功率随传播常数的增加而变大。

This review highlights the recent applications of non-linear optical (NLO) microscopy to study obesity-related health risks. A strong emphasis is given to the applications of coherent anti-Stokes Raman scattering (CARS) microscopy where multiple non-linear optical imaging modalities including CARS, sum-frequency generation (SFG), and two-photon fluorescence are employed simultaneously on a single microscope platform. Specific examples on applications of NLO microscopy to study lipid-droplet biology, obesity-cancer relationship, atherosclerosis, and lipidrich biological structures are discussed.

介绍了一种实现绝对定标单光子探测器量子效率的方法。该方法是利用自发参量下转换产生的纠缠光子对绝对定标单光子探测器量子效率。它的定标不确定度与传统方法相比,具有较好的一致性。同时,利用这一方法也使实现“无标准传递”的辐射定标成为可能。
