Variable Optical Attenuator Based on Long-Range Surface Plasmon Polariton Multimode Interference Coupler
The fabrication and characterization of a thermal variable optical attenuator based on long-range surface plasmon polariton (LRSPP) waveguide with multimode interference architecture were investigated. The surface morphology and waveguide configuration of Au stripe were studied by atomic force micro...
