我们研究了利用光子晶体中缺陷的引导模式来实现双共振。当激发和发射波长分别与局域导模和腔模同时共振时，光致发光增强了3个数量级以上。我们发现，局域导模对其中一个偏振缺陷的大小相对不敏感，允许灵活地控制波长组合。这种双共振技术有望在各种系统中增强光致发光和非线性波长转换效率。
We investigate the use of guided modes bound to defects in photonic crystals for achieving double resonances. Photoluminescence enhancement by more than three orders of magnitude has been observed when the excitation and emission wavelengths are simultaneously in resonance with the localized guided mode and cavity mode, respectively. We find that the localized guided modes are relatively insensitive to the size of the defect for one of the polarizations, allowing for flexible control over the wavelength combinations. This double resonance technique is expected to enable enhancement of photoluminescence and nonlinear wavelength conversion efficiencies in a wide variety of systems.
