Design and Implementation of Fiber-embedded Plasmonic Structures in Microwires

Abstract

Plasmonic structures can dramatically enhance photonic devices functionality [1] by providing controllable field confinement and light nanofocussing which are crucial for imaging, diagnostic, and sensing applications. Pure metallic tips or metal coated optical fibers have been demonstrated as fiber-compatible efficient plasmonic devices [2] but with limited applicability in real applications due to fragility and limited environmental robustness.
