Latest Patents

Qian Hu holds a patent for "Field reconstruction for an optical receiver." This invention describes an optical receiver capable of accurately measuring the phase and amplitude of received intensity- or amplitude-modulated optical signals through digital-signal processing. The patent outlines how the digital signal processor (DSP) reduces the detrimental effects of relative phase noise between the optical reference oscillator and the optical carrier. The DSP employs a sequence of digital filters to select a signal component that represents a non-vestigial modulation sideband, followed by signal equalization, which may include dispersion compensation. In some embodiments, the optical receiver can be a direct-detection optical receiver.
