We propose and numerically demonstrate an integrated fiber- coupled launcher for slow surface plasmon-polaritons. The device is based on a novel plasmonic mode-converter providing efficient power transfer from the fast to the slow modes of a metallic nanostripe. Total coupling efficiency with standard single-mode fiber approaching 30% (including ohmic losses) has been numerically predicted for a 25-μm long gold-based device operating at 1.55 μm telecom wavelength.

Abstract
We propose and numerically demonstrate an integrated fiber- coupled launcher for slow surface plasmon-polaritons. The device is based on a novel plasmonic mode-converter providing efficient power transfer from the fast to the slow modes of a metallic nanostripe. Total coupling efficiency with standard single-mode fiber approaching 30% (including ohmic losses) has been numerically predicted for a 25-μm long gold-based device operating at 1.55 μm telecom wavelength.File in questo prodotto:
