Light-emitting resonant structure driving raman laser
In a laser system, a set of substantially coherent electromagnetic radiation is applied as an input to a Raman laser. The Raman laser may be fabricated on the same integrated circuit as the source of the substantially coherent electromagnetic radiation or may be fabricated on a different integrated circuit as the source of the substantially coherent electromagnetic radiation.
1 . A laser system comprising:
a source of charged particles;
a resonant structure configured to be excited by particles emitted from the source of charged particles and configured to emit electromagnetic radiation at a predominant frequency representing the data to be transmitted, wherein the predominant frequency has a frequency higher than that of a microwave frequency; and
a Raman laser including an input for receiving the predominant frequency from the resonant structure.
2 . The laser system as claimed in claim 1 , wherein the resonant structure and the Raman laser are formed in a single integrated circuit.
