High-sensitivity modulation of electromagnetically induced transparency analog in a THz asymmetric metasurface integrating perovskite and graphene
文献摘要：
Active control of the electromagnetically induced transparency(EIT)analog is desirable in photonics develop-ment.Here,we theoretically and experimentally proposed a novel terahertz(THz)asymmetric metasurface struc-ture that can possess high-sensitivity modulation under extremely low power density by integrating perovskite or graphene.Using the novel metasurface structure with the perovskite coating,the maximum amplitude modulation depth(AMD)of this perovskite-based device reached 490.53％at a low power density of 12.8037 mW/cm2.In addition,after the novel THz metasurface structure was combined with graphene,this graphene-based device also achieved high AMD with the maximum AMD being 180.56％at 16.312 mW/cm2,and its transmission amplitude could be electrically driven at a low bias voltage.The physical origin of this modu-lation was explained using a two-oscillator EIT model.This work provides a promising platform for developing high-sensitivity THz sensors,light modulators,and switches.
