Abstract

Photonic waveguides with graphene can enable resonant coupling of the waveguide mode and the graphene plasmonic modes. We demonstrate theoretically that the plasmonic resonance in the hybrid waveguides can be significantly enhanced by employing a graphene nanoribbon with a deep subwavelength width when a lower-order graphene nanoribbon mode and a mode of a bare waveguide are efficiently coupled. A further increase is possible when a single graphene stripe is replaced by a finite array of graphene nanoribbons. This effect may provide a feasible platform for an efficient amplitude modulation which can be employed in the design of specific devices such as low-power modulators, filters, or sensors.

基于石墨烯等离子体共振的波导调幅器

石墨烯光子波导可以实现波导模式和石墨烯等离子体模式的共振耦合。我们从理论上证明，当低阶石墨烯纳米带模式和裸波导模式有效耦合时，采用深亚波长宽度的石墨烯纳米带可以显著增强混合波导中的等离子体共振。当单个石墨烯条纹被有限的石墨烯纳米带阵列所取代时，进一步的增加是可能的。这种效应为有效的幅度调制提供了可行的平台，可用于设计诸如低功率调制器、滤波器或传感器等特定器件。
