Phoenix in-line fiber polarizers have been in the market for over 12 years. The company can boast the highest extinction ratio, largest bandwidth devices available on the market. Phoenix employs industry proven optical fiber evanescent field technology to fabricate the polarizers, and over the years Phoenix engineers have refined and improved the process providing the highest quality product at globally competitive prices.
Phoenix fiber optic in-line 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.
