Simulations of hybrid long-range plasmon modes with application to 90 deg bends

摘要

We perform rigorous simulations of hybrid long-range modes guided by a central metal core and a two-dimensionaldielectric slab. We show that these modes are subject to fewer limitations than conventional long-range plasmon modes in terms of field confinement and guiding performance. These hybrid modes may offer substantial improvements for integrated plasmonic components, as illustrated here by the consideration of 90 deg bends.
