iXblue’s Polarizing (PZ) fiber is designed such that only one state of polarization is guided along the fiber; any other state of polarization will be lost rapidly thus yielding a high built-in polarization extinction ratio. This particular mechanism is obtained through a specific waveguide design and a careful optimization of the glass composition resulting in both high birefringence and leakage behavior. PZ fibers are available at different wavelengths with a broad polarizing window (typically larger than 100 nm), low attenuation and high extinction ratio (≥30dB), which can be tuned by coiling the proper fiber length at the appropriate coil diameter. Contrary to in-line polarizers, the PZ fiber-based polarizer is an all-fiber solution offering superior polarization extinction ratio, low loss and excellent stability over temperature.
