  • Communication system with QAM modulation
    Patent number: 9231705
    Abstract: A data communications network in which a first information-containing radio frequency signal input is applied to a modulation circuit for modulating a carrier wave with the signal input, and a second information-containing radio frequency signal is applied to at the modulation circuit for modulating least one of the constellation points of the first modulation.

  • External cavity laser with adaptive fiber bragg grating (FBG) for minimizing noise related to stimulated brillouin scattering (SBS) in dispersive fiber links
    Publication number: 20060109877
    Abstract: An optical transmitter including an external cavity laser for generating an optical signal, and transmitting the optical signal over a dispersive fiber optic link. The optical transmitter includes an electronic circuit coupled to the external cavity laser to change spectral characteristics of the external cavity laser through changing physical properties of the external cavity laser by providing a periodic stress or an aperiodic stress to the external cavity laser, thereby reducing an effect of noise in a received signal arising from stimulated Brillouin scattering (SBS) generated in the dispersive fiber optic link.
