1. A method for shifting the frequency of an electromagnetic beam carrying a telecommunication signal, the method comprising:
- generating in a material a polariton wave having a polariton wave frequency; and
directing the beam to interact with the polariton wave and cause at least portion of the beam to shift in frequency by an amount corresponding to the polariton wave frequency.
