Fiber Optic Polarizers
Phoenix fiber optic polarizers are produced by replacing the cladding in the locally processed region of the fiber with a polarization selective material. Within the polarizing region one polarization mode of the single mode fiber is highly attenuated and the other mode propagates with virtually no loss. Phoenix Fiber Polarizers readily achieve Extinction ratios above 50dB whilst maintaining extremely low transmission loss of the required polarization mode. Phoenix Photonics have been supplying Optical Fiber Polarizers into the market for over 9 years.
