Optical sensors are widely used in the biomedical, chemical and food industries. They
provide high sensitivity to changes in the refractive index of the environment due to a …

Long-range surface plasmon polaritons (LRSPPs) are optical surface waves that propagate
along a thin symmetric metal slab or stripe over an appreciable length (centimeters) …

Surface plasmon–polaritions, collective electron oscillations coupled to light waves at the
surface of a metal, show unique properties that are valuable in a broad range of scientific …

We propose several planar layouts of ultra-compact plasmonic modulators that utilize
alternative plasmonic materials such as transparent conducting oxides and titanium nitride …

This paper reviews the main physical aspects involved in plasmonic devices, which are
considered as a route to subwavelength devices and represents one of the most studied …

A surface plasmon polariton detector is demonstrated at infra-red wavelengths. The device
consists of a metal stripe on silicon forming a Schottky contact thereon and supporting …

The potential of surface plasmon waveguides for bulk and surface (bio) chemical sensing
was assessed theoretically, anticipating their use in an integrated optics sensor such as a …

Silicon-based photonic devices dissipate substantially less power and provide a significantly
greater information bandwidth than electronic components. Unfortunately, large-scale …

The key problem currently faced by plasmonics is related to material limitations. After almost
two decades of extreme excitement and research largely based on the use of noble metals …
