Microcavities provide the possibility to control and enhance light-matter interaction, which is indispensable for future quantum optical communication [1]. Microcavities with two identical periodically corrugated metallic mirrors supporting surface plasmon polaritons can further confine optical fields into a subwavelength regime. In this report, we demonstrate that mode interactions between surface plasmons and a microcavity mode can be used to tune mode dispersion, which is essential for light matter interaction. We study here numerically how the surface plasmons interact with the cavity modes in both near and far field regimes in a metallic meander cavity via tuning the excitation strength of the surface plasmons [2].
