Interference suppression based on power-dependent transfer function of angle-modulated optical links

  • US Patent No. 9654217
  • Issued: May 16, 2017
  • Status: Active

Systems and method are provided to for suppressing interference signals in optical systems, without prior knowledge of the type of location of the interferers, while maintaining a linear response to small signals of interest (SOI). By exploiting the unique power (or voltage) dependent transmission function of an externally angle-modulated photonic link, embodiments of the present disclosure are configured to provide strong, wideband interference suppression without requiring detailed knowledge of the interfering signal.
