Abstract :
A novel thermal controlled optical attenuator based on symmetric dielectric-loaded surface plasmon polariton (SDLSPP) waveguide is proposed and theoretically analyzed in this work. The mode effective indices, propagation lengths, the temperature dependent characteristic are analyzed using a finite-element method (FEM). Such device can be controlled by low driving power and shows excellent tunability. The optical attenuator provides a potential for novel temperature-tunable surface plasmon polariton (SPP) devices.
