Numerical optimization of a grating coupler for the efficient excitation of surface plasmons at an Ag-SiO2 interface

The efficient generation of surface plasmons from free space optical waves is still an open problem in the field. Here we present a methodology and optimized design for a grating coupler. The photoexcitation of surface plasmons at an Ag-SiO2 interface is numerically demonstrated to yield greater than 50% coupling from a Gaussian beam into surface plasmon voltages and currents.

Compact magnetic antennas for directional excitation of surface plasmons.

Plasmonics is considered as one of the most promising candidates for implementing the next generation of ultrafast and ultracompact photonic circuits. Considerable effort has been made to scale down individual plasmonic components into the nanometer regime. However, a compact plasmonic source that can efficiently generate surface plasmon polaritons (SPPs) and deliver SPPs to the region of inter...

Multicolor directional surface plasmon-coupled chemiluminescence.

In reports over the past several years, we have demonstrated the efficient collection of optically excited fluorophore emission by its coupling to surface plasmons on thin metallic films, where the coupled luminescence was highly directional and polarized. This phenomenon is referred to as surface plasmon-coupled emission (SPCE). In this current study, we have extended this technique to include...

Title Unidirectional Surface Plasmon-polariton Excitation by a Compact Slot Partially Filled with Dielectric Unidirectional Surface Plasmon-polariton Excitation by a Compact Slot Partially Filled with Dielectric References and Links

We propose a new scheme on unidirectional surface plasmonpolariton (SPP) excitation with the following advantages: ultracompact size, working at arbitrary incidence angle and over a wide spectrum. The proposed structure utilizes a partially filled metallic slot with dielectric to realize unidirectional SPP excitation via direct field manipulation. We theoretically and numerically show that unid...
