On the basis of a general analysis of waveguides containing a dispersive material, we identify conditions under which slow-light propagation may enhance the gain, absorption, or phase change. The enhancement is shown to depend on the slow-light mechanism and the translational symmetry of the waveguide. A combination of material and waveguide dispersion may strongly enhance the control of light speed, e.g., using electromagnetically induced transparency in quantum dots embedded in a photonic crystal waveguide.
在对包含色散材料的波导进行综合分析的基础上，我们确定了慢光传播可以增强增益、吸收或相位变化的条件。研究表明，增强依赖于慢光机制和波导的平移对称性。材料和波导色散的组合可以极大地增强对光速的控制，例如，在嵌入光子晶体波导的量子点中利用电磁感应透明。
