Latest Patents

One of Tatsuya Itoh's latest patents is for a polarization-maintaining optical fiber. This innovative fiber exhibits excellent polarization-maintaining performance and significantly low splice loss when connected to another polarization-maintaining optical fiber with a cladding diameter of 125 μm, even if the fiber has a smaller cladding diameter of about 80 μm. The design includes a core, a pair of stress-applying parts positioned radially outward from the core, and a cladding that surrounds both the core and the stress-applying parts. With a diameter of the stress-applying parts ranging from 21 μm to 32 μm and a distance between them of 6 μm to 17 μm, along with a relative refractive index difference of 0.3% to 0.5%, this invention achieves a sufficiently large mode field diameter (MFD), thereby reducing splice loss.
