Abstract

A variety of structures, methods, systems, and configurations can support plasmons for multiplexing.

Claims (20)

1. A plasmon multiplexer, comprising:

a first plasmon guide extending from a first input location to a first output location and transmissive of plasmon energy to a first receiver;

a first plasmon switch configured to receive a multiplexed plasmon signal, the multiplexed plasmon signal including first and second plasmon signals, and wherein the first plasmon switch is interposed at a first central location intermediate the first input location and first output location and responsive to a first control signal to selectively pass the first plasmon signal, while blocking the second plasmon signal;

a second plasmon guide extending from a second input location to a second output location and transmissive of plasmon energy to a second receiver different from the first receiver; and

a transmission guide positioned to transmit the multiplexed plasmon signal to the first plasmon guide and the second plasmon guide.

2. The plasmon multiplexer of claim 1 wherein the first input location corresponds substantially to the second input location.

3. The plasmon multiplexer of claim 1 wherein the transmission guide is supportive of a plasmon.

4. The plasmon multiplexer of claim 1 wherein the transmission guide includes a converter arranged to convert electromagnetic energy to a plasmon.

5. The plasmon multiplexer of claim 1 wherein the transmission guide includes an optical fiber.

6. The plasmon multiplexer of claim 1 wherein the first input location includes a converter arranged to convert electromagnetic energy to a plasmon.

7. The plasmon multiplexer of claim 1 wherein the second input location includes a converter arranged to convert electromagnetic energy to a plasmon.

8. The plasmon multiplexer of claim 1 wherein the first plasmon switch is further configured to selectively block the second plasmon signal.

9. The plasmon multiplexer of claim 1 wherein the first plasmon signal has a first modulation frequency and the second plasmon signal has a second modulation frequency different from the first modulation frequency.

10. The plasmon multiplexer of claim 1 wherein the first control signal includes plasmon energy.

11. The plasmon multiplexer of claim 1 wherein the first control signal includes electromagnetic energy and is configured to electromagnetically saturate the first plasmon switch.

12. A plasmon multiplexer, comprising:

a first plasmon guide extending from a first input location to a first output location and transmissive of plasmon energy to a first receiver;

a first plasmon switch configured to receive a multiplexed plasmon signal, the multiplexed plasmon signal including a first plasmon signal having a first plasmon frequency and a second plasmon signal having a second plasmon frequency different from the first plasmon frequency, and wherein the first plasmon switch is interposed at a first central location intermediate the first input location and first output location and responsive to a first control signal to selectively pass the first plasmon signal at the first plasmon frequency, while blocking the second plasmon signal at the second Plasmon frequency;

a second plasmon guide extending from a second input location to a second output location and transmissive of plasmon energy to a second receiver different from the first receiver; and

a transmission guide positioned to transmit the multiplexed plasmon signal to the first plasmon guide and the second plasmon guide.
