We demonstrate the realization of on-chip plasmonic analogue of electromagnetically induced transparency (EIT) in integrated plasmonic devices using detuned Fabry-Perot resonators aperture-side-coupled to a metal-insulator-metal (MIM) waveguide, with the transmission peak occurring at the intermediate wavelength. Strong MIM mode confinement along with localized side-coupling allows one to realize subwavelength photonic components with EIT-like transmission. Numerical results show that MIM components exhibiting pronounced EIT-like spectra in near infrared with the footprint of < 0.15 μm2 and group index of ~26 can be designed.
我们展示了在集成等离子体器件中，通过将失谐的法布里-珀罗谐振器孔径侧耦合到金属-绝缘体-金属（MIM）波导，实现电磁诱导透明（EIT）的片上等离子体模拟，传输峰出现在中间波长处。强大的MIM模式限制以及局部侧耦合使得人们能够实现具有类EIT传输的亚波长光子组件。数值结果表明，可以设计出在近红外波段表现出明显类EIT光谱的MIM组件，其尺寸小于0.15μm²，群折射率约为26。
