  • Optoelectronic filter and method for signal suppression
    Patent number: 9971226
    Abstract: An optoelectronic filter having at least one input and an output includes a modulator circuit having at least first and second inputs with a first one of the modulator circuit inputs adapted to couple to a respective one of the at least one input of the optoelectronic filter. The modulator circuit receives at least a first radio frequency (RF) signal having a first power level and a second RF signal having a second, different power level at the first one of the modulator circuit inputs and in response thereto generates a modulated signal at an output thereof. The first RF signal is suppressed relative to the second RF signal in the modulated signal. The optoelectronic filter additionally includes a light source adapted to couple to a second one of the modulator circuit inputs. A corresponding method is also provided.
