Abstract:
1. A method for establishing a transistor-like effect for a surface plasmon, said method comprising the steps of: A) providing an electro-optic substrate having a gate permittivity; B) placing a first conductive layer on said electro-optic substrate to establish an interface therebetween for transmission of said surface plasmon; C) forming a first plurality of grooves and a second plurality of grooves in said first conductive layer, said first plurality and said second plurality being spaced-apart from each other; D) establishing a source coupling region in said first plurality of grooves, a drain coupling region in said second plurality of grooves and a gate region in said interface; and, E) varying said gate permittivity with a varying means in direct contact with said conductive layer for selective propagation of said surface plasmon along said interface from said source region to said drain region.
