As an SPP propagates along the surface, it loses energy to the metal due to absorption. It can also lose energy due to scattering into free-space or into other directions. The electric field falls off evanescently perpendicular to the metal surface. At low frequencies, the SPP penetration depth into the metal is commonly approximated using the skin depth formula.

The electromagnetic waves are conducted through an optical waveguide. When light enters to the region with a thin metal layer, it evanescently penetrates through the metal layer exciting a Surface Plasmon Wave (SPW). In waveguide coupling configuration, the waveguide is created when the refraction index of the grating is greater than that of substrate. Incident radiation propagates along the waveguide layer with high refractive index.

Illustration of a Semiconductor Ring Laser (SRL). The laser cavity is a waveguide with a racetrack geometry (but this can also be another geometry), which enables it to lase in two counterpropagating directions: clockwise (CW) and counterclockwise (CCW). The light is evanescently coupled out of the cavity to a straight output waveguide. Semiconductor ring lasers (SRLs) are miniature ring laser devices with potential applications in optoelectronics, photonics and all-optical circuits.

Electro-optical devices have combined aspects of both optical and electrical devices in the form of a modulator as well. Specifically, electro-optic modulators have been designed using evanescently coupled resonant metal gratings and nanowires that rely on long-range surface plasmons (LRSP). Likewise, thermo-optic devices, which contain a dielectric material whose refractive index changes with variation in temperature, have also been used as interferometric modulators of SPP signals in addition to directional-coupler switches. Some thermo-optic devices have been shown to utilize LRSP waveguiding along gold stripes that are embedded in a polymer and heated by electrical signals as a means for modulation and directional-coupler switches.
