Latest Patents

One of his latest patents is for a low-dispersion single-mode optical fiber. This innovative fiber includes a core and a cladding that covers the core. The core has a relative refractive index difference of 0.30-0.65% and a radius of 2.5-4.5 μm. The cladding layer consists of first, second, third cladding layers, and an outer cladding arranged sequentially from inside to outside. The first cladding layer covers the core and has a relative refractive index difference of -0.70% to -0.30% and a radius of 4.5-7.5 μm. The second cladding layer covers the first cladding layer, with a relative refractive index difference of -0.20% to 0.25% and a radius of 7.0-12.0 μm. The third cladding layer covers the second cladding layer, featuring a relative refractive index difference of -0.60% to 0.00% and a radius of 10.0-20.0 μm. The outer cladding is made of pure silicon dioxide glass.

Another significant patent is for a bending-insensitive single-mode fiber with ultra-low attenuation. This fiber includes a core layer and multiple cladding layers. The core layer has a radius of 3.0 to 3.9 μm and a relative refractive index of -0.04% to 0.12%. The inner cladding layer surrounds the core layer and has a radius of 8 to 14 μm with a relative refractive index of -0.35% to -0.10%. The trench cladding layer has a radius of 14 to 20 μm and a relative refractive index of -0.6% to -0.2%. The auxiliary outer cladding layer has a radius of 35 to 50 μm and a relative refractive index of -0.4% to -0.15%. The outer cladding
