Latest Patents

Zhijian Liu's latest patents include a method for efficiently preparing doped optical fiber preforms and a small-diameter polarization maintaining optical fiber. The method for preparing a doped optical fiber preform involves formulating a rare earth material or a functional metal material with a co-doping agent into a doping solution. This solution is mixed with high-purity quartz powder, dried, crushed, and screened to obtain a doped quartz powder. The process continues with depositing the doped quartz powder onto a target rod to form a doped core layer, followed by the application of high-purity quartz powder to create a quartz outer cladding. The final step involves collapsing the structure at high temperatures to produce the doped optical fiber preform.

The small-diameter polarization maintaining optical fiber is designed to enhance stability characteristics of attenuation and crosstalk. It features a quartz optical fiber with inner and outer coatings, an optical fiber core layer, and a quartz cladding. The design includes two stress zones and a buffer coating, ensuring excellent performance at working wavelengths of 1310 nm and 1550 nm, with low attenuation and crosstalk values. This innovation lays the groundwork for advancements in high-precision optical fiber gyroscopes.
