Latest Patents
Changzun Zhou holds a patent 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 a polarization maintaining (PM) fiber using a narrowband fiber Bragg grating (FBG). The PM fiber includes a first narrowband reference FBG, which serves as a reference for measuring the SOP. The birefringence properties of the PM fiber allow the reference FBG to reflect two narrowband spectra, each with a central wavelength in the slow and fast axes. By measuring the intensity of these reflected spectra and adjusting the fiber with a polarization controller, it is possible to achieve a predetermined SOP. This method enables accurate measurements of optical properties, such as reflectivity, of optical devices according to the predetermined SOP.
