Latest Patents

Among his latest patents, the first one is an innovative optical fiber that features a chromatic dispersion slope that is shallow. This invention introduces a dispersion shifted monomode optical fiber that, in the wavelength range of 1400 nm to 1650 nm, exhibits both a chromatic dispersion maximum and a slope with an absolute value of less than 0.05 ps/nm·km. Notably, the maximum chromatic dispersion occurs at a single point within this wavelength range. Furthermore, this fiber also demonstrates a slope with an absolute value of less than 0.03 ps/nm·km in the narrower wavelength range of 1530 nm to 1580 nm, making it particularly suited for wavelength division multiplexed transmission systems.

His second patent revolves around dispersion compensating fiber tailored for wavelength division multiplexed optical fiber transmission systems. This monomode optical fiber boasts specific characteristics at a wavelength of 1550 nm, including a dispersion slope ranging from -0.8 ps/nm·km to -0.5 ps/nm·km, and a chromatic dispersion from -130 ps/nm·km to -90 ps/nm·km. The design features a unique index profile that includes a central part with a higher index than the cladding, a ring with a higher index than the cladding yet lower than that of the central part, and a trench with a lower index than the cladding. This innovative design allows the fiber to effectively compensate for dispersion, thereby finding applications in high bit rate transmission systems.
