Adjustable Optical Fiber In-line Polarizer for Custom Light Polarization
Kerns Tech's in-line fiber polarizers are designed to pass linearly polarized light while blocking the orthogonal polarization from an unpolarized (or randomly polarized) light source. They can attenuate the orthogonally polarized light with a high extinction ratio of at least 23 dB, depending on the specifics of each polarizer (see the tables below). These polarizers can also be used to enhance the extinction ratio of polarized signals. For the PM versions of these devices, the output polarization and 2.0 mm narrow key of the connector are aligned to the slow axis of the fiber. For FC/APC-terminated versions, the return loss will be higher than for FC/PC-terminated versions because the angled ferrule minimizes back reflections.
In-line fiber polarizers are ideal for fiber optic networks and measurement applications, including polarization analysis, polarization monitoring and control, polarization mode dispersion (PMD) monitoring, and polarization extinction ratio (PER) improvement. They work well with polarization-maintaining fiber amplifiers, fiber lasers, and high-speed communication systems and instrumentation.
