Surface plasmon polaritons locally excited on the ridges of metallic gratings.
With the perspective to achieve an in-depth understanding of metallic periodic surfaces, we study the surface plasmon polaritons that are locally excited on the ridges (between the indentations) of metallic lamellar gratings composed of slits or grooves. An approximate model and fully vectorial computational results show that the normalized excitation rate is rather small for slit arrays (appro...
متن کاملImaging slit-coupled surface plasmon polaritons using conventional optical microscopy.
We develop a technique that now enables surface plasmon polaritons (SPPs) coupled by nano-patterned slits in a metal film to be detected using conventional optical microscopy with standard objective lenses. The crux of this method is an ultra-thin polymer layer on the metal surface, whose thickness can be varied over a nanoscale range to enable controllable tuning of the SPP momentum. At an opt...
متن کاملNear-Field Optical Microscopy of Surface Plasmon Polaritons Nano-Optics
Near field optical microscopy techniques can be employed to characterize surface plasmon polaritons phenomena. These studies have set the stage for the current surge in the nano-optics field. In this chapter experiments and numerical developments conducted to the understanding of this area are outlined. Furthemore a scanning near-field microwave microscope is presented as an alternative techniq...
متن کاملLaser-fabricated dielectric optical components for surface plasmon polaritons.
Fabrication of dielectric optical components for surface plasmon polaritons (SPPs) by two-photon polymerization (2PP) is studied. This direct-write femtosecond laser technology provides a low-cost and flexible method for the fabrication and investigation of plasmonic structures and optical components. Using the 2PP technique, we fabricated narrow dielectric ridges with dimensions as small as 15...
متن کاملTransmission of surface plasmon polaritons through atomic-size constrictions
We study the excitation and propagation of surface plasmon polaritons (SPPs) on a micron-sized thin gold stripe. Grating couplers are embedded for both excitation of SPPs and detection after propagation. The experimental setup allows measuring of the decay length of the SPPs on the gold stripe excited in the near infrared part of the electromagnetic spectrum. We show that SPPs are transmitted w...
