The free-carrier dispersion effect with photo-excited free carriers provides all-optical control of the resonance of photonic crystal microcavities. Using this technique, a spatial light modulator comprising optically addressed cavity arrays has been developed for high-efficiency, high-bandwidth spatiotemporal modulation of light.

增强时空光调制器

光激发自由载流子的自由载流子色散效应提供了对光子晶体微腔共振的全光学控制。使用这种技术，已经开发了一种包含光学寻址腔阵列的空间光调制器，用于光的高效、高带宽时空调制。
