Resonance enhanced THz generation in electro-optic polymers near the absorption maximum

Research output: Journal Publications and ReviewsRGC 21 - Publication in refereed journalpeer-review

Abstract

The electro-optic (EO) coefficient of an organic nonlinear material exhibits a sharp resonance near the absorption maximum of the material. Due to this resonance, we experimentally observe the amplitude of the THz field generated from a 3.1-μm -thick EO polymer composite to be larger than that emitted from a 1000-μm -thick crystal of ZnTe. This comparison allows us to estimate the resonance enhanced EO coefficient of the polymer composite to be over 1250 pmV at 800 nm. © 2004 American Institute of Physics.
