Latest Patents

One of Jie Li's latest patents is titled "Broad bandwidth graded index multimode optical fiber for distributed temperature sensing in the 1550 NM region." This invention discloses a method for measuring temperature through distributed temperature sensing by transmitting light through a fiber optic cable. The method involves detecting backscattered light, calculating a ratio between the intensities of the anti-Stokes and Stokes bands, and using this ratio to determine the temperature being sensed. The fiber optic cable features a central core with a refractive index that decreases progressively from the center to the periphery, achieving a bandwidth-length product greater than 2000 MHz-km at 1550 nm.

Another notable patent is "Brillouin dynamic grating generation using dual-Brillouin-peak optical fiber." This invention outlines a method that includes injecting light of two different wavelengths into a wavelength division multiplexer, combining them to produce a third wavelength, and reflecting this light in a dual-Brillouin peak optical fiber. The dual-Brillouin peak optical fiber generates a Brillouin dynamic grating that enhances the back-reflected Brillouin signal of the combined light.
