【摘要】Giant resonance enhancement is demonstrated to be due to the Fano interference in a grating waveguide composed of gain-assisted silicon slabs.The Fano mode is characterized by its ultra-narrow asymmetric spectrum,different from that of a pure electric or magnetic dipole.The simulation indicates that a sharp Fano-interfered lineshape is responsible for the giant resonance enhancement featuring the small-gain requirements. 【总页数】5页(302-306) 【关键词】
