摘要: Transition of surface-plasmon resonance from out-of-plane photonic crystal effect is observed in a semiconductor array subwavelength holes by optical pump-terahertz probe measurements. The dielectric properties the photoexcited are essentially altered intense excitation due to photogenerated free carriers. As result, becomes metallic and favors coupling propagation surface plasmons. photoinduced resonant extremes agree well with Fano model.
