从光子晶体的传输矩阵理论出发，推导了掺杂饱和吸收非线性介质的光子晶体的缺陷模的透射率，以及缺陷层中局域光的增强因子。
The transmittance of defect mode in one dimension photonic crystals with nonlinear absorptional dielectric materials was deduced by the transfer matrix theory.
“这是我们这一发现的精要所在：采用局域模不仅能捕获光，还增强了光和物质的相互作用，”Lodahl说。
"This is the essence of our discovery: we used localized modes not just to trap light but to enhance interaction between light and matter," Lodahl says.
对光子晶体的性质和应用，如光局域化或光子晶体波导，甚至于是沿着一个很尖锐的弯曲的光子晶体波导能力，以及光子晶体激光器，进行了讨论。
The characteristics and applications of photonic crystal, such as light localization or the ability to guide light even along a sharp bend, and photonic crystal laser, are discussed.
