980nm/1060nm In-Line All-Fiber Polarizer
HanYu all-fiber evanescent-field polarizers replace the cladding of a short fiber section with polarization-selective material and package it as a polarizing region. One polarization is highly attenuated while the other passes with practically no attenuation. The non-invasive treatment leaves the core unaffected and maintains fiber transmission performance.

Applications
Polarization-sensitive sensing systems. Polarization-state definition; polarization analysis; polarization control; polarization-sensitive modules; fiber-optic sensing; test instruments.
Key Features
Extinction ratio up to50dB, very low loss and nearly zero back-reflection. The980nm/1060nm polarizers can work at one wavelength such as980nm or across a defined band. SM/SM extinction ratio increases with wavelength; operation outside the defined band is possible with potentially different specifications. PM versions provide stable extinction ratio within the defined range. Operation at 980-1080nm; high extinction ratio; low loss; compact, rugged packaging; all-fiber construction; near-zero back reflection.
