polarizing optical fiber

iXblue Polarizing (PZ) fiber is designed so 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 (≥ 30 dB), that can be tuned by coiling the proper fiber length at the appropriate coil diameter.

If needed iXblue also offers ready to use polarizing solutions based on PZ fibers.
