Optical carrier Brillouin processing of microwave photonic signals.
TLDR
In this article, a Brillouin signal processing based on modification of the optical carrier's magnitude and phase by stimulated Brillour scattering-induced depletion is proposed, which offers wideband processing and low noise and requires only low optical power.Abstract:
We introduce a novel concept in Brillouin signal processing based on modification of the optical carrier’s magnitude and phase by stimulated Brillouin scattering–induced depletion. The technique offers wideband processing and low noise and requires only low optical power. Application to the enhancement of a 25-km high-frequency analog link is experimentally demonstrated and yields a 6.5-GHz bandwidth extension and a 13-dB reduction in the link insertion loss without intermodulation distortion.read more
