Latest Patents
One of his latest patents is titled "Simultaneous interrogation of multi wavelength-modulated fiber optical sensors by modulating an arrayed waveguide grating based demultiplexer." This invention describes a compact interrogator designed for the simultaneous interrogation of multi wavelength-modulated fiber optical sensors. It includes a planar waveguide-based demultiplexer that receives input signals from the sensors. An array of detectors is coupled to the output waveguides of the demultiplexer, corresponding to different nominal wavelengths. A tuning element is utilized to match the nominal wavelengths of the output waveguide to the input signals from the respective sensors, allowing for the identification of the wavelengths of the individual sensors to be interrogated.
Another significant patent by Fengguo Sun is "Method and apparatus for measuring polarization-mode dispersion." This invention addresses the polarization-mode dispersion (PMD) of an optical device, such as fiber or component. It involves launching a first pump laser beam of a fixed wavelength, a probe laser beam with a second fixed wavelength, and a second pump laser beam with a variable wavelength and a polarization direction orthogonal to the other two beams into an optical device. This setup generates three output signals that are input into a semiconductor optical amplifier to produce four-wave mixing (FWM) products. The average PMD of the device is computed by measuring the power of the FWM products versus the wavelength of the second pump laser beam.
