An All-Optical Plasmon Modulator with a High Extinction Ratio Based on the Resonance of a Silver Block

Conventional all-optical modulators based on surface plasmon polaritons (SPPs) primarily utilize the nonlinear effect of a given material for modulation. Their performance is heavily dependent on the optical properties of the dielectric materials used and requires high pumping power. However, manipu...
