Abstract
A state-changeable device includes a first and a second particle arranged in proximity to each other; and a coupling material between the first and the second particle; wherein the first and the second particle are adapted to provide a charge carrier distribution such that surface plasmon polaritons (SPP) occur; and the coupling material is adapted to exhibit a variable conductivity in response to a trigger signal thereby changing an electro-optical coupling between the first and the second particle.
Claims10
A state-changeable device comprising:
- a first particle and a second particle, wherein the first particle and the second particle are either coated with a chemically-switched material coating, wherein metallic or conductive coupling is induced by a pH value change of a liquious environment or joined by a piezoelectric material that changes geometry in response to an external trigger thereby changing the spatial coupling and the corresponding surface plasmon polaritons (SPP) configuration wherein the first particle and the second particle are adapted to switch between conductive and insulating behavior.
A switching device comprising:
- at least one state-changeable device comprising:
- a first particle and a second particle;
- and
- a coupling material between the first particle and the second particle, wherein the first particle and the second particle are adapted to provide a charge carrier distribution such that surface plasmon polaritons (SPP) occur;
- and
- a first optical waveguide and a second optical waveguide arranged in cross-bar overlapping fashion having the at least one state-changeable device between the intersection region of the cross-bar configuration and coupled to the at least one state-changeable device.
