Latest Patents

Yunfei Zhao holds a patent for a method titled "Method for monitoring and measuring optical properties of device in polarization maintaining fibers by using reference fiber bragg grating and fiber components manufactured thereby." This innovative method provides a way to measure and monitor the state of polarization (SOP) of polarization maintaining (PM) fibers using a narrowband fiber Bragg grating (FBG). The method utilizes a first narrowband reference FBG to accurately assess the SOP of the PM fiber, taking advantage of the birefringence properties of the fiber. By measuring the intensity of the reflected spectra in both the slow and fast axes, and by tuning the fiber with a polarization controller, it is possible to achieve a predetermined SOP. This advancement allows for precise measurements of optical properties, such as reflectivity, of optical devices according to the predetermined SOP.
