  • Amplification of long-range surface plasmons with reduced noise
    Patent number: 8660163
    Abstract: An optical amplifier suitable for coherently amplifying surface plasmon-polariton waves with high gain and low noise over visible and infrared wavelengths. The optical amplifier is comprised of a thin strip of material having a complex permittivity with a negative real part, in contact on at least one side with an optical gain medium, where the strip has finite width and thickness such that optical radiation couples to the strip and propagates along its length as a surface plasmon-polariton wave. The surface plasmon-polariton amplifier can also be incorporated into a resonant cavity to form a plasmon-polariton laser.
